List of top Physics Questions on AC Circuits asked in WBJEE

A resistor of resistance 'R' draws power 'P' when connected to an AC source. If an inductance is now placed in series with R, such that the impedance of the circuit becomes 'Z', the power drawn will be
For a domestic AC supply of 220 V at 50 cycles per sec, the potential difference between the terminals of a two-pin electric outlet in a room is given by
When an AC source of EMF $E$ with frequency = 100 Hz is connected across a circuit, the phase difference between $E$ and current $I$ in the circuit is observed to be $\pi/4$ as shown in the figure. If the circuit consists of only RC or RL in series, then
When an AC source of EMF
