To determine the resistance of a voltmeter by discharging a capacitor through it, the instantaneous voltage is then given by the relation:
Correct answer: A. A
- A. A
- B. B
- C. C
- D. D
Explanation
Option A is the correct option since Voe-t/RC gives the correct instantaneous voltage.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
