$A$ choke coil is used to control:

An alternating voltage $v(t) = 220 \sin(100 \pi t) \text{ V}$ is applied to a purely resistive load of $50 \, \Omega$. The time taken for the current to rise from zero to half of its peak value is ..... $ms$.

$A$ $50 \mu F$ capacitor is connected to a $110 V, 60 Hz$ $AC$ supply. Determine the rms value of the current in the circuit. (in $A$)

An $AC$ voltage of $10 \sin \omega t$ volt is applied to a pure inductor of inductance $10 \ H$. The current through the inductor in ampere is

The current flowing in a coil is $3 \text{ A}$ and the power consumed is $108 \text{ W}$. If the a.c. source is of $120 \text{ V}, 50 \text{ Hz}$,the resistance in the circuit is (in $\Omega$)

An inductor is connected to an $AC$ source of frequency $50 \ Hz$. The frequency of the instantaneous power developed in the circuit is (in $Hz$)
