Question

What is the principle of capacitor? Find an expression for the capacitor of a parallel plate capacitor

Answer 1

Explanation:

A capacitor works on the principle that the capacitance of a conductor increase appreciably when an earthed conductor is brought near it. Thus a capacitor has two plates separated by a distance having equal and opposite charges.

Answer 2

Answer:

If the separation between the plates is much smaller than the size of plates, the electric field strength between the plates may be assumed uniform. This is a general expressionfor capacitance of parallel plate capacitor.
