उत्तर
An A.C. generator produced an output voltage e = 170 sin 327t volt, where t is in seconds. The frequency of A.C. voltage is nearly 52 Hz.
Explanation:
Comparing given equation with the standard form,
`"e" = "e"_0 "sin" omega"t we get," omega = 2pi"f"`
`therefore 2 pi"f" = 327 Rightarrow "f" approx 52 "Hz"`
