NEET Physics RLC Circuits MCQ Question
Consider a series RLC circuit where the inductance (L) and capacitance (C) are adjusted such that the system is at resonance. Which of the following statements about the voltage across the resistor (R) is correct?
The voltage across R is equal to the source voltage.
The voltage across R is zero.
The voltage across R is equal to the voltage across L.
The voltage across R is equal to the voltage across C.
Correct Answer
Detailed Explanation
At resonance in a series RLC circuit, the voltages across L and C cancel each other because they are out of phase, leaving the total source voltage to appear across R.
