• Increase the surface area of the plates

• Reduce the surface area of the plates

• Increase the distance between the plates

• Reduce the distance between the plates

• Insert a dielectric between the plates

Answer 1

The voltage across the capacitor can be increased by the following:

Reduce the surface area of the plates

Increase the distance between the plates
