The reactance of a coil when used in the domestic $ac$ power supply $(220\, V, 50\, Hz)$ is $100\, \Omega$. The self-inductance of the coil is nearly........$H$.

An $A.C.$ source is connected to a resistive circuit. Which of the following is true?

The same current is flowing in two alternating circuits. The first circuit contains only an inductor and the other contains only a capacitor. If the frequency of the $AC$ emf is increased,what will be the effect on the value of the current?

$A$ choke coil is used as resistance in

$A$ $50 \mu F$ capacitor is connected to a $110 V, 60 Hz$ $AC$ supply. Determine the rms value of the current in the circuit. (in $A$)

Let $f = 50\, Hz$ and $C = 100\, \mu F$ in an $AC$ circuit containing a capacitor only. If the peak value of the current in the circuit is $1.57\, A$,the expression for the instantaneous voltage across the capacitor will be (assuming current is $I = I_m \sin(\omega t)$):
