3.2 When unequal charges are placed on the two plates
3.0 Parallel Plate Capacitor
Two metallic parallel plates of any shape but of same size and separated by a small distance constitute parallel plate capacitor. Suppose the area of each plate is $A$ and the separation between the two plates is $d$. Also assume that the space between the plates contains vacuum.3.2 When unequal charges are placed on the two plates
