What is capacitor? Principle working, types and how it works

Case 1# The area of the plates parallel to each other. The capacitor has an area of plates very much. So it is the greater the capacitance. Case 2# If the distance between the plates is greater, it will reduce the capacitance. Case 3# Change the dielectric substance. It causes the capacitance to change, as well.
