The capacitance of a 0–1000 V electrostatic voltmeter increases from 36 pF to 42 pF from zero to full-scale deflection. It is required to extend the range of the voltmeter to 10000 V by using an external series capacitor. What should be the value of this series capacitor to ensure proper full-scale deflection?
- 14.667 pF✓
- 24.200 pF
- 33.600 pF
- 40.800 pF
Correct answer
4.667 pF
