An alternating $e.m.f.$ of angular frequency $\omega$ is applied across an inductance. The instantaneous power developed in the circuit has an angular frequency

As per the given graph,choose the correct representation for curve $A$ and curve $B$. Where $X_{C} =$ reactance of a pure capacitive circuit connected to an $A.C.$ source,$X_{L} =$ reactance of a pure inductive circuit connected to an $A.C.$ source,$R =$ resistance of a pure resistive circuit connected to an $A.C.$ source,and $Z =$ impedance of the $LCR$ series circuit.

Inductive reactance . . . . . .

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

Same current is flowing in two different $A.C.$ circuits. The first circuit contains only an inductance $(L)$ and the second contains only a capacitance $(C)$. If the frequency of the $A.C.$ source is increased in both circuits, what will happen to the current?

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 $\pi$)
