What does AC stand for in physics?

O A.

alternating current

B. alternative circuit

OC. alternating composition

OD. all charge

Ac stands for Alternating Current.

Explanation:

Alternating Current -

alternating current is defined as that current that alters and reverses direction, in contrast to DC, DC follows single direction.

AC circuits reverses as the current changes the direction. AC electricity is created by an AC electric generator, that determines the frequency.

The voltage can be readily changed, thus making it more suitable for long-distance transmission than DC electricity.

Advantages:

The AC is easy to generate than DC It is cheaper to generate ac than DC. The AC generators have higher efficiency than DC. The loss of energy during transmission is negligible for AC. The AC can be easily converted into DC The variation of AC can easily be done using transformers either step up or step down. The value or magnitude of ac can be decreased easily without loss of excess of energy. This can be done by using choke coil.

The answer would be A (alternating current)
