Question

brief about AC current​

Answer 1

Answer:

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

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

AC can come in a number of forms, as long as the voltage and current are alternating.

We often want to describe an AC waveform in mathematical terms. For example we will use the common sin wave. There are three parts to sine wave - Amplitude, frequency and phase.

$\bigstar$An alternating current (AC) is an electric current of which magnitude and direction vary, unlike direct current, whose direction remains constant.

$\bigstar$This means that the direction of current flowing in a circuit is constantly being reversed back and forth.

$\bigstar$This is done with any type of AC voltage source.
