Question:
A coil having 'n' turns and resistance 'R'Ω is connected with a galvanometer of resistance '4R' Ω. What is the induced current in the circuit when this combination (coil+galvanometer) is moved in time t from a magnetic flux Φ1 to Φ2?

- $ \frac{-n(Φ_2-Φ_1)}{4Rt}$
- $ \frac{-n(Φ_2-Φ_1)} {Rt}$
- $\frac{-n(Φ_2-Φ_1)}{ 5Rt}$
- $\frac{(Φ_2-Φ_1)}{ nRt}$
