The inductive reactance of an inductor of $\frac{1}{\pi } \, H$ at $50 \, Hz$ frequency is.....$\Omega$.

Obtain an equation for the current when an $AC$ voltage is applied to an inductor and draw a graph of $V$ and $I$ versus time.

In which circuit is the average power consumed maximum?

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

$A$ 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:

$A$ capacitor '$C$' is connected across a $DC$ source,the reactance of the capacitance will be . . . . . . .
