Assertion: When capacitive reactance is smaler than the inductive reactance is `LCR` circuit, e.m.f. leads the current.
Reason : The phase angle is the angle between the alternating e.m.f. and alternating current of the circuit.

Assertion (A) : when capacitive reactance is less than the inductive reactance in a series LCR circuit, e.m.f. leads the current. Reason (R) : The angle by which alternating voltage leads the alternating current in series RLC circuit is given by tan varphi = (X_(L) - X_(C))/(R) .
