Consider a capacitor has vacuum in the space between the conductors. If we double the amount of charge on each conductor, what happens to the capacitance?
Correct answer: C. It remains same
- A. It increases
- B. It decreases
- C. It remains same
- D. It depends on the size or shape of the conductors
Explanation
When the charge given to the capacitor becomes double the capacitance of the capacitor remains the same .The capacitance depends only on the geometrical configuration of the conductors.The capacitance of a capacitor is affected by the area of the plates, the distance between the plates, and the ability of the dielectric to support electrostatic forces.

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.
