The voltage of an ac supply varies with time \( (t) \) as
P \( \mathrm{V}=120 \sin 100 \pi t \cos 100 \pi t \). The maximum

W voltage and frequency respectively are
(1) 120 volts, \( 100 \mathrm{~Hz} \)
(2) \( \frac{120}{\sqrt{2}} \) volts, \( 100 \mathrm{~Hz} \)
(3) 60 volts, \( 200 \mathrm{~Hz} \)
(4) 60 volts, \( 100 \mathrm{~Hz} \)
