Problems from Electricity

  1. 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?
  2. 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: C= A\varepsilon /d

and substituting , C= 1 F, A = 1.1 x 108, \varepsilon = 8.8 x 10-12,

we get  , d =9.68×10-4 metres
