When an AC source of e.m. f. is connected across a circuit, the phase difference between the e.m.f. e and the current i in the circuit is observed to be as shown in the diagram. If the circuit consists possibly only of RC or RL in series, find the relationship between the two elements.
As the current i leads the voltage by it is an RC circuit, hence,
From all the given options only option (1) is correct.
