Capacitance of a capacitor increases with a decrease in:
Correct answer: D. Plate separation
- A. Dielectric constant
- B. Plate area
- C. Permittivity
- D. Plate separation
Explanation
Increasing the plate separation (d) decreases the capacitance, as the capacitance is inversely proportional to the distance between the plates. This is because a greater distance requires a larger voltage to store the same amount of charge.

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.
