Which of the following graphs represents the variation of inductive reactance $(X_{L})$ with the frequency of the voltage source $(\nu)$?

$A$ $44 \; mH$ 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.

$A$ choke coil is used to control:

An $A.C.$ source is connected across a pure inductor. Which one of the following figures shows the correct phase relation between the current and $e.m.f.$?

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:

$A$ capacitor of capacity $C$ has reactance $X$. If capacitance and frequency become double then reactance will be
