A capacitance of a capacitor is not affected by:
Correct answer: B. Thickness of plates
- A. Distance between plates
- B. Thickness of plates
- C. Area of plates
- D. All of the above
Explanation
The capacitance of a capacitor is determined by the formula C = ε(A/d), where ε is the permittivity of the dielectric material, A is the area of one of the plates, and d is the distance between the plates. Therefore, capacitance is affected by both the area of the plates and the distance between them, but not by the thickness of the plates. Option B is correct because the thickness of the plates does not come into play in the formula for capacitance. Options A and C are incorrect because they are factors that do influence capacitance.

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.
