MHT CET 2024 Physics question
An e.m.f. is applied to the L-R circuit. The inductive reactance is equal to the resistance 'R' of the circuit. The power consumed in the circuit is
Answer: (3)
Solution
Impedance of the L-R circuit: since . The rms emf is and the rms current is . Power is dissipated only in the resistance: $P =
