In the case of a parallel plate capacitor, when the distance between the two plates is reduced to half and the area of the plate doubled, the capacitance
Correct answer: A. Increases four times
- A. Increases four times
- B. Increases six times
- C. Is doubled
- D. Remains the same
Explanation
When the distance between the plates is reduced to half and the area of the plates is doubled, the capacitance increases to four times its original value.

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.
