Capacitance of a parallel plate capacitor depends upon:
Correct answer: A. All of these
- A. All of these
- B. Area of plate
- C. Distance between the plates
- D. Dielectric constant
Explanation
The capacitance of a parallel plate capacitor is directly proportional to the area of one of the plates (A) and the dielectric constant of the medium between the plates (k). Additionally, it is inversely proportional to the distance between the plates (d).Mathematically,(εo is the permittivity of free space with a value of 8.85 x 10-12 F/m).

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.
