An ac current varies through one complete cycle in 0.01 second. What is the period and frequency? If the current has a maximum value of 5Ampere ?

The period is the time it takes for one complete cycle of the current. In this case, the period is 0.01 seconds.

The frequency is the number of cycles per second. It is the reciprocal of the period. So, the frequency is 1/0.01 = 100 cycles per second or 100 Hz.

The maximum value of the current is 5 Ampere.
