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
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 :
The magnetic flux linked to a circular coil of radius R is
