The…………… of alternating current varies …………………….. With time and its………………….is reversed

Define, alternating current and give its expression.

Reverse saturation current of a diode

The frequency of an alternating current is 50 Hz. What is the minimum time taken by current to reach its peak value from rms value ?

What is meant by alternating current? Define its ampliude and time period.

The peak value of an alternating current is 5 A and its frequency is 60 Hz. Find its rms value and time taken to reach the peak value of current starting from zero.

State the rms value of an alternating current? Write the relation between the rms value and peak value of an alternating current that varies with time
