An `AC` source is rated at `220V, 50 Hz.` The time taken for voltage to change from its peak value to zero is

A

50 sec

B

0.02 sec

C

5 sec

D

`5 xx 10 ^(-3) ` sec

Text Solution

Verified by Experts

The correct Answer is:
D
Time required ` = (T)/(4) = (1)/(4f) = (1)/(4 xx 50) = (1)/(200)`
`= 5 xx 10 ^(-3) ` sec
