A parallel plate capacitor consists of two large plane parallel conducting plates separated by a small distance.
The electric field in different regions is: Outer region I (region above the plate 1),
Outer region II (region below the plate 2),
In the inner region between the plates 1 and 2, the electric fields due to the two charged plates add up, giving
For uniform electric field
The capacitance C of the parallel plate capacitor is then
