Question on: JAMB Physics - 2001
At reasonance, the phase angle in an a.c. circuit is
A
90°
B
60°
C
0°
D
180°
Ask EduPadi AI for a detailed answer
Correct Option: C
At resonance in an AC circuit, the inductive reactance (XL) equals the capacitive reactance (XC). This results in the impedance of the circuit being purely resistive. Since the voltage and current are in phase in a purely resistive circuit, the phase angle is 0°.
