NEET Physics Resonance MCQ Question
Which of the following statements about resonance in an RLC circuit is correct?
Resonance occurs when the inductive reactance equals the capacitive reactance.
Resonance can occur in both RL and RC circuits.
In a resonant circuit, the current amplitude is independent of the source voltage.
Resonance leads to a decrease in the total impedance of the circuit.
Correct Answer
Detailed Explanation
Resonance in an RLC circuit occurs when the inductive reactance (XL) equals the capacitive reactance (XC), allowing for maximum current flow. This is specifically noted in the context of RLC circuits, where both L and C must be present for resonance to occur.
