An inductance of $1 \ H$ is connected in series with an $AC$ source of $220 \ V$ and $50 \ Hz$. The inductive reactance (in ohm) is: (in $\pi$)

$A$ coil of inductance $L$ has an inductive reactance of $X_L$ in an $AC$ circuit in which the effective current is $I$. The coil is made from a superconducting material and has no resistance. The rate at which power is dissipated in the coil is

$A$ $0.7\,H$ inductor is connected across a $120\,V, 60\,Hz$ $AC$ source. The current in the inductor will be very nearly: (in $,A$)

An alternating voltage of $22 \, V$ is applied across an inductance coil of reactance $11 \, \Omega$. If the inductance of the coil is $0.07 \, H$, the frequency of the alternating voltage is: (in $ \, Hz$)

Obtain the formula for current when an $AC$ voltage is applied to a capacitor and draw the graphs of $V$ and $I$ versus $\omega t$.

The inductive reactance of a coil is $X_{L}$. If the inductance of a coil is tripled and the frequency of the $A.C.$ supply is doubled,then the new inductive reactance will be
