Question

what is AC Nd DC........?​

Answer 1

Answer:

Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction. ...

The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.

Answer 2

$\huge\boxed{\boxed{\fcolorbox{white}{pink}{Answer}}}$

Alternating Current (AC):

Alternating current describes the flow of charge that changes direction periodically. As a result, the voltage level also reverses along with the current. AC is used to deliver power to houses, office buildings, etc.

AC can be produced using a device called an alternator. This device is a special type of electrical generator designed to produce alternating current.

Direct Current (DC):

Direct current is a bit easier to understand than alternating current. Rather than oscillating back and forth, DC provides a constant voltage or current.

DC is defined as the "unidirectional" flow of current; current only flows in one direction. Voltage and current can vary over time so long as the direction of flow does not change.
