NEET Physics RLC Circuits MCQ Question
In a series RLC circuit, if the resistance R is 100 Ω and the circuit is driven at its resonant frequency with an applied maximum voltage of 10 V, what is the amplitude of the current?
0.1 A
0.05 A
0.2 A
0.5 A
Correct Answer
Detailed Explanation
At resonance, the impedance is purely resistive, so the current amplitude i_m = v_m / R. Here, v_m = 10 V and R = 100 Ω, so i_m = 0.1 A.
