Chapter 5 Capacitance and Dielectrics
A capacitor is a device which stores electric charge. Capacitors vary in shape and size, but the basic configuration is two conductors carrying equal but opposite charges (Figure
8.2: Capacitors and Capacitance
The capacitance (C) of a capacitor is defined as the ratio of the maximum charge (Q) that can be stored in a capacitor to the applied voltage (V) across its plates. In …
Field between the plates of a parallel plate capacitor using Gauss''s Law
Edit: Also, another problem I noticed was that even if we remove the negative plate from the capacitor and then apply Gauss''s Law in the same manner, the field still comes out to be …
