Ans.Both supply voltage and circuit current are in phase with each other. Q.2.What is the phase relationship between the supply voltage and current flowing through a purely inductive circuit? Ans.In a purely inductive circuit current lags behind the supply voltage by 90° or π/2 radians. Q.3.Why are the inductors usually iron cored? Ans.Inductors or choke…
