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

141 Hz, 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
E = 141sin(628t)
`underset(rms)(E)` = `underset(o)(E)`/`sqrt 2` = 141/141 = 100 V and `2pi`f = 628
`adr` f = 100 Hz
