Figure given below shows a graph of emf `'epsilon'` generated by an ac generator verses time. What is the frequency of the emf?

A

10Hz

B

0.10Hz

C

20Hz

D

50Hz

Text Solution

Verified by Experts

The correct Answer is:
A
Time period = 0.1 sec.
Frequency of the emf is given by
`f=(1)/(T) =(1)/(0.1) =10Hz`
