Question

The voltage of an ac supply varies with time $(t)$ as $V = 120 \sin 100 π tcos 100 π t .$ The maximum voltage and frequency respectively are

Moderate

A

120 volts, 100 Hz
B

$\frac{120}{\sqrt{2}}$ volts, 100 Hz
C

60 volts, 200 Hz
D

60 volts, 100 Hz

Solution

$V = 120 \sin 100 πt \cos 100 πt \Rightarrow V = 60 \sin 200 πt V_{\max} = 60 V and ν = 100 Hz$
