Capacitance of a partially filled parallel plate capacitor

For a capacitor, whatever insulator goes between conductor plates, is a dielectric. If one dielectric material fills up half the thickness between plates, the other half is air, and you have a mixed dielectric capacitor.

You can calculate the capacitance value by considering two capacitors in series, each having the thickness of individual dielectric thickness. Watch these two videos to learn more...

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.
