MHT CET 2024 Physics question
An inductance coil has a resistance of . When on AC signal of frequency 480 Hz is applied to the coil, the voltage leads the current by . The inductance of the coil in henry is
Answer: (D)
Solution
For a series R-L circuit the phase angle by which voltage leads the current is given by . With , , so . Then \dfrac{X_L}{ω}\dfrac{80}{2π×480}$ =
