Homework Statement
if the separation between the plates of an isolated charged parallel-capactior is increased, why does the stored electrostatic energy increase?
Homework Equations
C=eA/d
e= permitivity of space
The Attempt at a Solution
i do not know the equation of electrostatic energy, is it E = (1/4πεo)Q/r2?
if so, then if distance increase, the radius in this here equation would increase therefore the electrostatic energy should be lowered?
