Question

If a dielectric substance is introduced between the plates of a charged air-gap capacitor, the potential energy of the capacitor will :

Answer 1

become k times the original

Answer 2

The capacitance of a set of charged parallel plates is increased by the insertion of a dielectric material. Thecapacitance is inversely proportional to the electric field between the plates, and the presence of the dielectricreduces the effective electric field.hence PE increases
