- The parallel plates of an air filled capacitor with area of area 1.1 x 10^8 m^2 . What must be the width of the plate be if the Capacitance is 1 Farad?
- Four capacitor each of 2microfarad are connected in such a way that total capacitance is also 2microfarad. Show what combination gives this value. Also try to illustrate the diagram.

Answer

1.Using the formula:

and substituting , C= 1 F, A = 1.1 x 10^{8}, = 8.8 x 10^{-12},

we get , d =9.68×10^{-4} metres
