Difference Between AC And DC. In this article, you will come to know about what is AC, what is DC, what is the main difference between AC and DC, and a comparison between AC vs DC.

Both the terms are the types of current flow. The current flow in two directions: an AC (alternating current) and DC (direct current). The difference between these two types of currents lies in the directions of the current flow. Here, we will first discuss the main difference between AC and DC, then differentiate them in detail.

What Is The Main Difference Between AC And DC?

The main difference between AC and DC is that the:

-AC is the current flow in which it flows in the forwarding and backward directions. It keeps switching directions.

-DC is the current flow in which it flows in a single straight direction steadily.

What Is AC?

AC stands for ‘Alternating Current’. In this electric charge flow, the current changes its directions periodically. It means it flows in the forward and backward directions. AC is very common and preferred electric power for household items.

It was first tested in 1832 on the principles of Michael Faraday, using Dynamo Electric Generator. It can be identified in a waveform called sine wave or curved line. These curved lines are referred to as electric cycles and measured per second. The measurement of AC is Hertz or Hz. It is generally used in electric motors which are used in washing machines, refrigerators, air conditioners, and many appliances.

What Is DC?

DC is the current flow in which it flows in a single straight direction steadily. In this type of current flow, the current does not change periodically. It supplies power to electrical devices and is used to charge batteries. The direct current is the combination of plus and minus signs, a dotted line or a straight line. Every device that runs on a battery, uses an AC adapter to get charged. It power relies on DC. Some examples of devices that run
on DC are:
-Mobile phone batteries.
-Laptop batteries.
-Cell phones.
-Electric vehicles.
-Flashlights.
-Flat screens.
-Television.

Comparison Between AC And DC:

-AC stands for Alternating Current.
-DC stands for Direct Current.

-AC keeps changing its directions.
-DC flow in a straight line.

-AC has a frequency of 50 Hz to 60 Hz.
-DC has no frequency or zero frequency.
