... Ch 26.4 – Energy Stored in a Capacitor – charging a capacitor To charge the capacitor, an external agent (battery) must do work to separate the charges. Step by step, the battery “grabs” a small amount of charge dq off one capacitor plate and move it to the other. At first, this requires no work, b ...

Comparing with Fig. 1 it is seen that the absorption edge is also a function of the DQW dimensions since this leads to different values for the maximum bind ...
