The abbreviation AC stands for Alternating Current. It’s a current in which the direction of electric charge movement changes on a regular basis. In other words, alternating current varies its direction and magnitude on a regular basis; it starts at zero, increases to maximum, returns to zero, grows to maximum in the opposite direction, and then returns to zero. As long as the AC is flowing in the circuit, this cycle will be repeated indefinitely. Unlike direct current, which only travels in one direction, alternating current flows in both directions. When compared to DC, AC is much easier to generate and transmit. As a result, in mains-wired facilities such as residences, factories, and buildings, it is the AC that is utilized.
Advantages of AC:
Step up transformers can be used to transfer AC over great distances, but this is not possible with DC.
AC is less expensive and easier to generate and transmit than DC.
The AC generator has a higher efficiency than the DC generator.
When transmitting AC, there is extremely little power loss.
It is possible to convert AC to DC.
Without wasting much energy, the magnitude of AC can be reduced.
Brushes are required in DC motors to make electrical contact with moving wire coils, but they are not required in AC motors.
The surrounding communication wires, such as telephone lines, are less disturbed by AC.
It can be used in both home and industrial settings.
