If a dielectric is placed between two plates of a capacitor, the net capacitance:
Correct answer: B. Increases
- A. Decreases
- B. Increases
- C. Remains constant
- D. Becomes zero
Explanation
The dielectric placed between the plates of the capacitor reduces the electric field strength between the plates of the capacitor, this results in a small voltage between the plates for the same charge. The capacitor stores more charge for a smaller value of voltage. Therefore, 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.
