B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
In a series LCR (Inductor-Capacitor-Resistor) circuit, the phase angle (B8) between the e.m.f. (voltage) and the current can vary depending on the relative values of resistance (R), inductance (L), and capacitance (C). The possible phase angle ranges from 0 to C0/2 radians. This occurs because the circuit can behave as purely resistive (0 radians) when R dominates at low frequencies, or as inductive (approaching C0/2 radians) when the inductive reactance is significantly larger than the resistive component. Therefore, Option A is correct.
