Workdone & Energy Stored in a Capacitor

Workdone in a Capacitor:

The work done in a capacitor is the workforce required to move a unit positive charge from infinity to that point.

W = qV                

W = F × d 

Fd = qV

Therefore   F = \( \frac{qV}{d} \) 

But E = \( \frac{qV}{d} \; \times \; \frac{1}{q}\) 

But E = \( \frac{\not{q}V}{d} \; \times \; \frac{1}{\not{q}}\) 

E = \( \frac{V}{d} \)

Energy Stored in a Capacitor:

A capacitor is a two-terminal electrical device that can store energy in the form of an electric charge. Initially, the charge on the plates is q =
