A coil having resistance 20Ω and inductance 0.10H is connected across a 230V, 50Hz single-phase AC supply.
(a) Calculate the inductive reactance of the coil.
(b) Determine the impedance of the coil.
(c) Find the rms value of the current drawn from the supply.
(d) Compute the phase difference between the supply voltage and the coil current, and hence obtain the time lag of the current with respect to the voltage maxima.
