MHT CET 2026 Physics question
When an inductance 'L' and resistor R are connected in series to 25V, 50 Hz supply, a current of 0.5 A flows in the circuit. The current lags behind in phase from applied voltage by radian. The value of R is
Answer: (B)
Solution
Impedance of the circuit . For a series LR circuit the phase angle satisfies , so .
