A moving coil galvanometer has resistance 50 Ω and it indicates full deflection at 4 mA current. A voltmeter is made using this galvanometer and a 5 kΩ resistance. The maximum voltage, that can be measured using this voltmeter, will be close to:
  1. 40 V
  2. 15 V
  3. 20 V
  4. 10 V

Solution


Vmax=4×10-3×50+4×10-3×5×103
Vmax=20.2 V
