Question

What is Direct Current(DC)?

Answer 1

Answer :-

Alternating Current (AC) is a type of electrical current, in which the direction of the flow of electrons switches back and forth at regular intervals or cycles. ... Direct current (DC) is electrical current which flows consistently in one direction.

This form of power is most commonly produced by sources such as solar cells, batteries, and thermocouples. DC power is widely used in low voltage applications such as charging batteries, automotive applications, aircraft applications and other low voltage, low current applications.

Answer 2

Answer:

Direct current is the one directional or unidirectional flow electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams.
