If an alternating voltage is represented as
`E=141 sin (628 t)`, then the rms value of the voltage and the frequency are respectively

A

141V, 628 Hz

B

100 V, 50 Hz

C

100 V, 100 Hz

D

141 V, 100 Hz

Text Solution

Verified by Experts

The correct Answer is:
C
`V_"rms" = V_"max"/sqrt2 = 141/sqrt2` = 100 volt
t=100 Hz
