Video on Factors affecting a Parallel Plate Capacitor

This video in particular explains about the factors wch effects the capacitance of the capacitor, namely the area of the plates, distance between the plates and the nature of the medium separating the plates.
I'm also impressed about the type of parallel plate being used in this video. In most of the text bk example and numerical we just focus and talk about the parallel plate being rectangular but infact they can be of any geometrical shape, in this particular example a circular shaped plates are being used, but can be some other planar shaped also. This idea can be used in framing numericals. Just remember the formula for the area of the shape given. In this case its being circular hence area (A=pi.r^2), rest formula for the capacitance remains the same.
