In a choke coil,the reactance $X_L$ and resistance $R$ are such that

$A$ capacitor of $50 \mu F$ is connected to a power source $V = 220 \sin 50 t$ (where $V$ is in volt and $t$ is in second). Find the value of the $rms$ current (in ampere).

An $AC$ alternating $emf$ $E = 110 \sqrt{2} \sin(100t) \text{ V}$ is applied to a capacitor of $2 \mu F$. The $rms$ value of current in the circuit is $...... \text{ mA}$.

The voltage across a pure inductor is represented by the following diagram. Which of the following diagrams will represent the current?

An alternating voltage $E = 200 \sqrt{2} \sin(100 t) \text{ V}$ is connected to a $1 \mu\text{F}$ capacitor through an $A.C.$ ammeter. The reading of the ammeter shall be: (in $\text{ mA}$)

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?
