Lecture Notes on Capacitance

Here are some of the formula's which can be used while solving the numericals...

Variations of C, V and Q for an air capacitor when dielectric slab is inserted between the plates of Capacitor. The discussion shows both the conditions (i) when the battery is removed and then the dielectric slab is inserted and (ii) when the battery remain connected and then the dielectric slab is inserted.

Many Numerical Problems are based on such concepts and they are generally a favorable thinking ground for question framing. So master this concept well for any of your examinations.
