The average value of alternating current over a complete cycle is

The $r.m.s.$ value of the current $i = 3 + 4 \sin(\omega t + \pi/3)$ is:

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

If an alternating current is given by $i = a \sin(\omega t) + b \cos(\omega t)$,then the $rms$ value of the current is

The frequency of an alternating voltage is $50 \text{ cycles/sec}$ and its amplitude is $120 \text{ V}$. Then the $r.m.s.$ value of voltage is ........ $V$.

The sinusoidal potential difference $V_1$ shown in the figure is applied across a resistor $R$,producing heat at a rate $W$. What is the rate of heat dissipation when the square wave potential difference $V_2$ as shown in the figure is applied across the same resistor?
