Question

What is meant by the term frequency of an alternating current?

Answer 1

In an AC, the direction of the current is constantly changing from positive to negative and negative to positive.
The number of times the direction changes per second is called the frequency of the current.
In India the frequency is 50 Hz(50 times per second).
AC is better than DC for carrying current over long distance because it minimizes losses.
