If the plate area, plate separation, dielectric strength, and dielectric constant all are doubled for a parallel plate capacitor, what happens to the maximum voltage before breakdown occurs for this capacitor?

Question

Quizplus · Accepted Answer

The maximum voltage before breakdown occurs for a parallel plate capacitor is given by:V = Edwhere:V is the voltageE is the dielectric strengthd is the plate separationIf the plate area, plate separation, dielectric strength, and dielectric constant all are doubled, then the maximum voltage before breakdown occurs will quadruple. This is because the dielectric strength is doubled, and the plate separation is doubled, which means that the voltage required to cause breakdown will be four times greater.
