$A$ choke coil has

In an $ac$ circuit,an alternating voltage $e=200 \sqrt{2} \sin 100 t$ volts is connected to a capacitor of capacitance $1 \; \mu F$. The rms value of the current in the circuit is ..... $mA$.

$A$ choke coil is used as resistance in

In an $AC$-circuit containing only capacitance,the current

When an $A$.$C$. source is connected across a pure capacitor,the correct phase relation between current $(i_c)$ and voltage $(e_c)$ is shown in the figure.

The capacitive reactance of a capacitor $C$ is $X \ \Omega$. Both the frequency of the $A.C.$ supply and the capacitance of the capacitor are doubled. The new capacitive reactance will be:
