A coil of 0.01-henry inductance and 1-ohm resistance is connected to 200 volt, 50 Hz ac supply. Find the impedance of the circuit and time lag between max. alternating voltage and current.

Inductance L is given as 0.01 H

Resistance R is given as 1 ohm

Voltage is given as 200 V

Frequency is given as 50 Hz

Impedance is given Z = 3.3 ohms

Phase difference will be 72 × π/180 rad

0.004 sec is the Time lag in the alternating voltage and the current.
