In an AC circuit, resonance occurs when the impedance of the circuit is:
Zero
Maximum
Equal to the capacitive reactance of the circuit
Minimum
Correct answer is D
Resonance in an AC circuit occurs when the inductive reactance (XL) is equal to the capacitive reactance (XC). This is because at this point, the two reactances cancel each other out, leaving only the resistance of the circuit. As a result, the impedance of the circuit is minimized.
