By increasing the area of the plates and decreasing the distance between them, the capacitance of a capacitor:
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Remains unchanged
- D. Depending upon temperature
Explanation
If the plates of a capacitor are made larger, they can hold more charge, and if the plates are moved closer together, the electric field between them becomes stronger. Both of these changes allow the capacitor to store more charge for the same voltage, so the capacitance increases.

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.
