NEET Physics Resonance MCQ Question
Consider a circuit diagram depicting a series RLC circuit used for tuning a radio. The circuit includes a resistor (R), inductor (L), and variable capacitor (C) connected to an AC source. If the circuit is in resonance with a radio signal frequency, which of the following statements is true about the voltages across the inductor and capacitor?
The voltages across L and C cancel each other out because they are out of phase.
The voltages across L and C add up to double the source voltage.
The voltage across L is zero and across C is maximum.
The voltages across L and C are equal and in phase.
Correct Answer
Detailed Explanation
In resonance, the voltages across the inductor and capacitor cancel each other out because they are out of phase, allowing the total voltage to appear across the resistor.
