The capacitance of capacitor depends upon
Correct answer: D. All
- A. area of the plates
- B. distance between the plates
- C. dielectric between them
- D. All
Explanation
The capacitance (C) of a capacitor depends on three main factors:1. *Area of the plates (A)*: Increasing the area of the plates increases the capacitance, as more charge can be stored.2. *Distance between the plates (d)*: Decreasing the distance between the plates increases the capacitance, as the electric field between them becomes stronger.3. *Dielectric between them (ε)*: The dielectric material between the plates affects the capacitance, as it determines the strength of the electric field and the amount of charge that can be stored.The capacitance of a capacitor is given by the formula:C = ε₀εₐA/dwhere:ε₀ = vacuum permittivityεₐ = relative permittivity of the dielectric materialA = area of the platesd = distance between the plates

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.
