# Difference Between AC and DC

What You'll Learn?

Alternate Current (AC) and Direct Current (DC) are the two types of current flow and the major difference between AC and DC, DC also known as Direct Current electricity does not have this advantage over AC Alternate Current also known as electricity because the voltage levels of AC electricity can be easily converted to high or low voltage levels, while DC voltages canâ€™t be easily converted.

AC electricity has the advantage over DC because of its high voltage, which is more efficient for sending electricity over long distances.

## What is AC

Alternating current (AC) power is that the standard electricity that comes out of power outlets and is defined as a flow of charge that exhibits a periodic change in direction. In AC, the flow of the electrical charge changes its direction periodically. AC is that the most typically used and most preferred power for household equipment, office, and buildings, etc. it was first tested, supported the principles of Michael Faraday in 1832 employing a Dynamo Electric Generator.

Alternating current is often identified in a waveform called a wave, in other words, it will be said because of the curved line. These curved lines represent electric cycles and are measured per second. The measurement is read as Hertz or Hz. AC is employed in powerhouses and buildings etc because generating and transporting AC across long distances is comparatively easy. AC is capable of powering electric motors which are used on refrigerators, washers, etc

## What is DC

Unlike AC, the flow of electricity doesnâ€™t change periodically. the present electricity flows in a very single direction during a steady voltage. the most important use of DC is to produce power for electrical devices and also to charge batteries. Example: portable batteries, flashlights, flat-screen television, and electric vehicles. DC has a mix of plus and minus sign, a dotted line or a straight line. Everything that runs on an electric battery and uses an AC adapter while plugging into a wall or uses a USB cable for power relies on DC.

Examples would be cellphones, electric vehicles, flashlights, flat-screen TVs (AC goes into the TV and is converted into DC).

## Difference Between AC and DC

Alternating current Direct current
AC is the alternating current and it is the most commonly used electrical power DC is the direct current and its uses to supply power to the electrical devices and also to charge batteries
Distance
it can transfer to the long-distance even between the cities it cannot travel long distance as it losses the electrical power
Frequency
Generally, 50 HZ to 60 HZ or depend upon the country No frequency
Efficiency
High Less
Power Consumption
Less More

## Conclusion

Hence after examination of the Difference between AC and DC, we conclude that AC, the flow of electricity doesnâ€™t change periodically. the present electricity flows in a very single direction during a steady voltage and DC is to produce power for electrical devices and also to charge batteries
