NEET 2022 Phase 1 | Electromagnetic Induction and Alternating Current Question 18 | Physics

A series LCR circuit with inductance 10 H, capacitance 10 $$\mu$$F, resistance 50 $$\Omega$$ is connected to an ac source of voltage, V = 200sin(100t) volt. If the resonant frequency of the LCR circuit is v₀ and the frequency of the ac source is v, then

$${v_0} = v = 50$$ Hz

$${v_0} = v = {{50} \over \pi }$$ Hz

$${v_0} = {{50} \over \pi }$$ Hz, $$v = 50$$ Hz

$$v = 100$$ Hz, $${v_0} = {{100} \over \pi }$$ Hz
