Question

The current which changes direction after an equal interval of time is known as

Answer 1

Alternating current:

1. Alternating Current (AC) is that type of electrical current, in which the direction of the flow of electrons turns back and forth at regular intervals or cycles.
2. Current flowing in industrial power lines and normal household electricity that comes from a wall outlet is alternating current.
3. Alternating current (AC) is an electric current that periodically reverses its direction, in contrast to direct current (DC) which only flows in a single direction and cannot change periodically.
4. An alternating current is produced by switching the potential between two terminals in a fixed time interval.
5. The difference in potential between the positive and negative terminals is expressed in volts.
6. Because the unit for current is ampères, or amps, the symbol for it is “A” with a wavy line over it.
7. AC is that form of current that is mostly used in different appliances.
8. Some of the main examples of alternating current are audio signals, radio signals, etc.
9. An alternating current has a lot of advantages over DC as AC is able to transmit more power over large distances without any great loss of energy.

Thus, the current which changes direction after an equal interval of time is known as Alternating current (AC).
