An e.m.f. E = E_0 t is applied to circuit containing L and R in series. If X_L = 2R, then the power dissipated in the circuit is

MHT CET 2024 Physics question

An e.m.f. is applied to circuit containing L and R in series. If , then the power dissipated in the circuit is

Answer: (B)

Impedance of the series LR circuit: . The rms emf is , so . Average power dissipated only in the resistance: I_{rms}^2R\dfrac{E_0^2}{2·5R^2}$· R =
