MHT CET 2025 Physics question
In LCR series circuit, when ‘L’ is removed from the circuit, the phase difference between voltage and current in the circuit is . If ‘C’ is removed from the circuit instead of L then phase difference is again . The power factor of the circuit is ()
Answer: (D)
Solution
With L removed we have an RC circuit: , so . With C removed we have an RL circuit: , so . Hence : the full LCR circuit is at resonance, and its impedance
