An alternating voltage is represented by $V = 80 \sin(100 \pi t) \cos(100 \pi t) \text{ V}$. The peak voltage is (in $\text{ V}$)

The peak voltage of the $ac$ source is equal to:

An alternating current is given by $I = I_A \sin \omega t + I_B \cos \omega t$. The r.m.s. current will be

An alternating current is given by the equation $i = i_{1} \sin \omega t + i_{2} \cos \omega t$. The rms current will be

An $AC$ source is rated $222 \,V, 60 \,Hz$. The average voltage is calculated in a time interval of $16.67 \,ms$. It

$A$ sinusoidal voltage produced by an $AC$ generator at any instant $t$ is given by the equation $V = 311 \sin(314t)$. The $rms$ value of voltage and frequency are respectively:
