Physics · Current Electricity
When a resistance of 5 Ω is shunted with a moving coil galvanometer, it shows a full-scale deflection for a current of 250 mA. However, when a 1050 Ω resistance is connected with it in series, it gives a full-scale deflection for 25 V. The resistance of the galvanometer is:
- 1100 Ω
- 275 Ω
- 350 Ω✓
- 425 Ω
Correct answer
50 Ω
