Find the frequency of voltage for an AC circuit. The equation of alternating voltage is `V=200 sin 314 t.`

A

50 Hz

B

60 Hz

C

55 Hz

D

65 Hz

Text Solution

Verified by Experts

(a) Comparing `V=200 sin 314t` with the standard equation `V=V_(0)sinomegat," we get "omega=314s^(-1)`
Linear frequency, `f=(omega)/(2pi)=(314)/(2xx3.14)=50` Hz
