$A$ 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:

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?

The average value of alternating current $I = I_0 \sin \omega t$ in the time interval $[0, \frac{\pi}{\omega}]$ is:

$A$ multimeter reads a voltage of a certain $A$.$C$. source as $ 100 \,V $. What is the peak value of voltage of the $A$.$C$. source (in $\,V$)?

The variation of the instantaneous current $(I)$ and the instantaneous emf $(E)$ in a circuit is as shown in the figure. Which of the following statements is correct?

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