Question

The capacitance of a parallel-plate capacitor can be increased by

Answer 1

The capacitance of a parallel-plate capacitor can be increased by increasing the plate's surface area .The distances between the plates are being reduced. a dielectric with a greater permittivity

Answer 2

Explanation:
In this question, It is asked what all factors may be considered for the capacitance of a parallel-plate capacitor to increase it's value.
Following are the factors that can increase the capacitance of a parallel-plate capacitor:

1. By increasing the area of the plates that is kept parallelly.
2. Decreasing the distance between the plates.
3. A dielectric of higher permittivity value needs to be considered.
