The United States dollar or American dollar is the legal tender of the United States, its dependencies and other countries. The dollar is the most important international reserve currency in the world and also the most used in international transactions. Its status as the world's reference currency has made it the official currency of several countries and the de facto currency in many others, who use their paper money for current transactions or give a fixed exchange rate to their national currencies against the dollar. The Federal Reserve System is the nation's central bank and is also in charge of issuing dollars.

The currency code for this is USD.

The dollar was divided into 100 cents and the authority to mint coins in dollars and cents was given by the coinage act, which was approved in 1792. The US dollar's value has been fixed at 24,057 grams of fine silver or 20.67 dollars per troy ounce since 1836, and it has been green on its bills. The gold standard act of 1900 was the first to peg the dollar solely to gold. The pound sterling was the world's leading reserve currency after the end of World War II, but the dollar became a major reserve currency after the end of World War I.

In 1934, its equivalence with gold was revised up to 35 dollars per troy ounce, a value that it would maintain over several decades, until in 1971 it was definitively disassociated from the gold standard, for which reason the currency became, de facto, a fiat currency.

Fourteen other countries use the name "dollar" for their currency, which is different from the United States' issuance of this class of dollars.

For their part, other nations have used it as their official currency or as a substitute for their own weakened currency, such as El Salvador, Panama and East Timor.

The total amount of physical currency in circulation was 2.10 billion, of which 2.05 billion was in the form of Federal Reserve notes and 50 billion in the form of US coins and other bonds or notes.

There are many different versions of the origin of the $ symbol. The evolution of the New Spanish and Spanish abbreviation Ps, which is abbreviated as pesos, piastres, or pieces of eight, is said to be the reason why it is the most widely accepted. This theory is based on the study of manuscripts from the 18th and 19th centuries.

The symbol was used before the adoption of theUSD.

The city's Spanish colonial mint is believed to have inspired the symbol.

The Potos mine was in the current country of Bolivia. The mintmark was composed of the letters PTSI superimposed on top of each other, forming a symbol very similar to the dollar sign. The English colonies in North America used Spanish silver reales in common use. The Potos mine would be where the majority of those coins would be made. Potos became the largest city in all of America and the world's largest silver mine because it was the largest in history.

The variant with two vertical bars is still being used. The idea of superimposing U and S for the United States is sometimes attributed to the fact that it already existed by the time the area was a British colony.

The reales of 8 called columnarios appeared in the coins of the Mint of Mexico, and the symbol would be a depiction of the Pillars of Hercules. The band with the legend " Plus Ultra" was wrapped around it and the vertical bars were the columns. The gold and silver ingots that traveled in the Fleet of the Indies were stamped with a seal with this shape on it. The two bar original is simplified by the single bar version.

The dollar symbol is similar to the sestertius, which could suggest a Roman origin. In ancient manuscripts, the sestertius symbol is not visible with the vertical strokes on the letter S.

Exchange rates and prices vary because the world's currencies are tied to each other according to capital flows. The lattice system of leagues gives value.

For a long time, the dollar was the basis for world prices and exchange rates.

There is a tug of war between the leagues that unite the world's currencies.

The dollar reserve system is a part of the crisis because it drives cash into the US.

A new reserve system was suggested by him. Zhou Xiaochuan, the governor of the Chinese central bank, called for the creation of a new currency and for the International Monetary Fund to issue it.

Every year since 1972 the United States has produced its official coins.

Congress has the power to borrow money from the United States on credit, and it can do this by authorizing the Federal Reserve Banks to issue Federal Reserve Notes. These notes are "obligations of the United States" and "will be exchanged for lawful money at the United States Department of the Treasury, in the city of Washington (District of Columbia), or at any Federal Reserve Bank". Federal Reserve notes are by law the "legal tender" for the payment of debts. On the other hand, Congress has authorized the issuance of more than 10 types of dollar banknotes throughout the country. of history, although the Federal Reserve note is the only one that has remained in circulation since the 1970s.

The Federal Reserve Notes are printed on cotton fiber paper, which is a different type of paper than regular paper.

The "large-size notes" issued before 1928 measured 188.5 mm × 79.4 mm, while the small notes introduced that year measure 155.96 mm × 66.29 mm × 0.11 mm. The dimensions of modern US (small-size) notes size) are identical to the size of the Philippine peso bills issued during the United States administration after 1903, which enjoyed great success among the population.

The denominations are $1, $2, $5, $10, $20, $50, and $100. The notes above $100 were taken out of circulation in 1969. In 1969 President Richard Nixon issued an executive order to stop the circulation of these notes because they were being used in organized crime deals. They became even less necessary with the advent of electronic banking.

The $100,000 note, which was only issued as a 1934 series gold certificate and never publicly circulating, is illegal because it was produced in denominations of $500, $1,000, $5,000, $10,000, and $100,000. High denominations and uncirculated notes have become collector's items and are more valuable than their face value.

The series after 2004 have other colors in them to better distinguish denominations. The American Council of the Blind petitioned the Bureau of Engraving and Printing for physical changes to the bills.

Thetactile feature was planned to be added to the next redesign of the bills, except the $1 and $100 bills. Increasing the size of the numerals and giving them greater contrast is one of the things that will be done to help the visually impaired.

The colonial notes were issued by the Massachusetts Bay Colony.

The "continental currency" that lost its value in the war of independence was one of the new currencies that emerged.

Between the 16th and 19th centuries, the reference currency for international trade between Europe, Asia and America was historically the 8 real, also known in English as the "Spanish dollar", thanks to the fact that it established a standardized and global system of silver, an abundant metal thanks to its massive extraction in the Spanish colonies and which guaranteed the durability of the currency over time. The US dollar derived directly from the real of 8. The Spanish real would be replaced by the pound sterling and the gold standard in the last quarter of the 19th century.

The US dollar began to replace the pound as the hegemonic international reserve currency from the 1920s, as the country emerged unscathed from World War I and was a major recipient of gold during the conflict. After the United States became the hegemonic superpower after World War II, the Bretton Woods agreement of 1944 established an international monetary system where the US dollar became the main reserve currency and reference currency in world trade. The United States held 75% of the gold reserves at the time, with a value of $35 per troy ounce. The rest of the important currencies maintained a fixed exchange rate against the dollar, an exchange rate that each country ensured through its monetary policy and the help of the International Monetary Fund and the World Bank. This system ended in 1971. , when the dollar left the gold standard, although the currency continued to play a leading role that continues to this day.

The green color of the dollar is due to the fact that the Treasury Department began issuing "demand notes" called "greenbacks" in the 19th century.

The US dollar is one of the major world currencies in the Special Drawing Rights basket of currencies.

The central banks of all countries have large reserves of dollars on their deposits and are major buyers of United States Treasury bills and notes. The dollar has been the primary reserve currency worldwide since the end of the World War II, although since its peaks in the 1970s its share has been progressively declining —from almost 85% in 1975 to 59% in 2020.

The Eurodollars are not related to the euro and are held by foreign companies, organizations, and individuals. 80% of the dollars that individuals hold outside of the banking system are in the form of $100 bills.

The ability to impose sanctions on foreign companies and individuals is one of the things that the United States Department of the Treasury has the power to do.

The US dollar is the predominant standard monetary unit in which goods are quoted and traded and with which payments are settled in world commodity markets. In the latter market, the influence of the dollar is so strong that Historically, there is a rule that when the dollar strengthens, the price of raw materials falls, since it is the reference currency for most commodities. The dollar index is an important indicator of the strengths or weaknesses of the dollar. dollar against the six most important foreign currencies.

The United States government is able to borrow trillions of dollars from the global capital markets because of its strength. The benefit for the State minimum interest rates is almost certain.

Foreign governments and companies that can't borrow in their own local currency are forced to issue US dollar-denominated debt, which brings with it higher interest rates and greater risk of default. The ability of the United States to borrow in its own currency without facing a crisis in its balance of payments is often described as an "exorbitant privilege".

There is a permanent debate on whether or not monetary policies to consolidate a "strong dollar" are beneficial for the United States and for the entire world due to the fluctuations in the price of the dollar. Historically, the US government has preferred a strong dollar to a devalued one, which entails lower interest rates for the country and a greater capacity to import products and borrow, although as a counterpart, a rising dollar reduces export competitiveness to the US. ., resulting in its strong trade deficit.

A transformer is a static device that transfers alternating electricity from circuit to circuit at the same frequency, but the voltage level usually varies. For economic reasons, electrical energy must be transmitted at high voltage while it must be used at low voltage from a safety point of view. This increase in transmission voltage and reduced voltage for use can only be achieved using the step-up transformer and step-down transformer.

The main difference between the step-up and step-down transformer is that the step-up transformer increases the output voltage, while the step-down transformer reduces the output voltage.

The step-up transformer is a type of transformer with the function of converting low voltage (LV) and high current from the transformer's primary side to high voltage (HV) and low current value on the transformers' secondary side.

The step-down transformer is a type of transformer that converts high voltage (HV) and low current from the primary side of the transformer to low voltage (LV) and high current value on the secondary side of the transformer.

- When the output (secondary) voltage is greater than the input (primary) voltage, it is called a step-up transformer. In comparison, the output (secondary) voltage of the step-down transformer is smaller.

- In a step-up transformer, the low voltage winding is the primary coil, and the high voltage winding is the secondary winding. In contrast, in a step-down transformer, the low voltage winding is the secondary winding.

- In a step-up transformer, the current and magnetic field develop less on the secondary, and it grows high on the primary. In contrast, in a step-down transformer, the secondary end's voltage is lower due to there, the high current and magnetic field.

* Note1: The electric current is proportional to the magnetic field.

* Note2: According to Ohm's Law, the voltage is proportional to the amperage. If we increase the voltage more than the amperage will also increase, but in the transformer to transmit the same amount of electricity, if we increase voltage, then current will decrease and versa. Therefore, the capacity is constant in the send and receive terminals of the transformer.

- In a step-up transformer, the primary coil is made up of thick insulated copper wire, and the secondary is made up of thin insulated copper wire. In contrast, in a step-down transformer, the high output current results in the insulating copper thick are used to fabricate the secondary coil.

*Note3: The thickness of the wires depends on the electric current's ability to flow through them.

- The step-up transformer extends the voltage from 220v-11kv or more, while the step-down transformer reduces voltage from 440-220v, 220-110v or 110-24v, 20v, 10vv.

The same transformer can be used as a step-up transformer or step-down transformer. It depends on how it is connected in the circuit. If the input supply is supplied on the low-voltage winding, it becomes a step-up transformer. On the other hand, if the input power is supplied on the high voltage winding, the transformer becomes a step-down transformer.
