The coil of inductance $0.25 mH$ has a reactance of $330 \Omega$,when connected to an a.c. source. The frequency of the a.c. source is (Take $\pi = \frac{22}{7}$) (in $kHz$)

There is no resistance in the inductive circuit. Kirchhoff's voltage law for the circuit is

In a circuit,the current lags behind the voltage by a phase difference of $\pi / 2$. The circuit will contain which of the following?

The coil of a choke in an $AC$ circuit:

$A$ $44 \; mH$ inductor is connected to a $220 \; V, 50 \; Hz$ $AC$ supply,and a $60 \; \mu F$ capacitor is connected to a $110 \; V, 60 \; Hz$ $AC$ supply. What is the net power absorbed by each circuit over a complete cycle? Explain your answer.

The inductive reactance of a coil is $R \ \Omega$. If the inductance of the coil is tripled and the frequency of the $A.C.$ supply is also tripled,then the new inductive reactance will be:
