An alternating voltage $V(t) = 220 \sin(100 \pi t)$ volt is applied to a purely resistive load of $50 \ \Omega$. The time taken for the current to rise from half of the peak value to the peak value is: (in $ms$)

What is the phase difference between voltage $V$ and current $I$ in an $AC$ circuit containing only a capacitor?

In a circuit,the current lags behind the voltage by a phase difference of $\pi / 2$. The circuit will contain which of the following?

In $AC$ circuits,a choke coil is preferred over resistors because:

$A$ small signal voltage $V(t) = V_0 \sin(\omega t)$ is applied across an ideal capacitor $C$. Which of the following statements is correct?

$A$ $44 \; mH$ inductor is connected to a $220 \; V, 50 \; Hz$ $AC$ supply,and a $60 \; \mu F$ capacitor is connected to a $110 \; V, 60 \; Hz$ $AC$ supply. What is the net power absorbed by each circuit over a complete cycle? Explain your answer.
