DC is a commonly used abbreviation in the field of electricity and electronics. It stands for Direct Current.

Let's understand what direct current is and how it differs from alternating current (AC).

What is the Full Form of DC?

The full form of DC is Direct Current.

It refers to the uni-directional flow of electrons through a conductor such as a wire or cable.

What is Direct Current (DC)?

In direct current, the electrons always flow in the same direction from negative to positive.

The voltage in DC remains constant as opposed to alternating.

Some common sources that supply DC power are batteries, solar panels, fuel cells etc.

Characteristics of Direct Current:Unidirectional flow of electric chargeSteady voltage that does not alternateUsed in low voltage applications and electronicsEasier to store than alternating currentCan be generated from mechanical sourcesDifference from Alternating Current:AC voltage and direction alternates periodicallyAC is used for high power transmission over gridsAC generating sources: electric generators, utility power gridsAC is more complex to use than DC

In summary, direct current or DC refers to the steady uni-directional flow of electricity in a circuit. It is widely used in batteries, automobiles, electronics and low voltage systems.
