When a circuit element X is connected across an a.c. source, a current of √2A flows
through it and this current is in phase with the applied voltage. When another element Y is
connected across the same a.c. source, the same current flows in the circuit but it leads the
voltage by /2 radians.(i) Name the circuit elements X and Y. (ii) Find the current that flows
in the circuit when the series combination of X and Y is connected across the same a.c.
voltage.

(i) X-ResistorY-Capacitor(ii)Given,I=VR=2 When the series combination of X and Y is connected across the same a.c voltage,I=VR2+XC2=VR2  [ R=XC]Or I=22=1 A
