Consider a pure inductive $A$.$C$. circuit as shown in the figure. If the average power consumed is $P$, then

Capacitive reactance of a capacitor in an $AC$ circuit is $3 \ k\Omega$. If this capacitor is connected to a new $AC$ source of double frequency,the capacitive reactance will become:

When an a.c. source is connected across a pure resistor, the correct phase relation between current $(i_R)$ and voltage $(e_R)$ is shown in which figure?

$A$ coil has an inductance of $2 \ H$. The ratio of its reactance when it is connected first to an $A.C.$ source and then to a $D.C.$ source is:

An $a.c.$ of frequency $f$ is flowing in a circuit containing only an ideal choke coil of inductance $L$. If $V_0$ and $i_0$ represent peak values of the voltage and the current respectively,the average power given by the source to the choke coil is equal to

$A$ capacitor of $50 \mu F$ is connected to a power source $V = 220 \sin 50 t$ (where $V$ is in volts and $t$ is in seconds). The value of the rms current (in amperes) is:
