An inductor of inductance 2 mH is connected to a 220 V, 50 Hz ac source. Let the inductive reactance in the circuit is X1. If a 220 V dc source replace the ac source in the circuit, then the inductive reactance in the circuit is X2. X1 and X2 respectively are :
A standard filament lamp consumes 100 W when connected to 200 V ac mains supply. The peak current through the bulb will be :
Given below are two statements
Statement I : In an a.c circuit, the current through a capacitor leads the voltage across it.
Statement II : In a.c circuit containing pure capacitance only, the phase difference between the current and voltage is \(\pi\).
In the light of the above statements, choose the most appropriate answer from the options given below
In a series LCR circuit, the inductance \(L\) is \(10 ~\mathrm{mH}\), capacitance \(C\) is \(1 ~\mu \mathrm{F}\) and resistance \(R\) is \(100 ~\Omega\). The frequency at which resonance occurs is :-
An ac source is connected to a capacitor C. Due to decrease in its operating frequency
A \(12 \mathrm{~V}, 60 \mathrm{~W}\) lamp is connected to the secondary of a step down transformer, whose primary is connected to ac mains of \(220 \mathrm{~V}\). Assuming the transformer to be ideal, what is the current in the primary winding ?
