When an alternating voltage of is applied across a device , a current of A flows through the circuit and it leads the applied voltage by an angle radian. When the same voltage source is connected across another device , the same current is observed in the circuit but in phase with the applied voltage. What is the current when the same source is connected across a series combination of and ?
