The relationship between capacitor principle and structure

Capacitor

Capacitors with high capacitance will store large amount of electric charge whereas the capacitors with low capacitance will store small amount of electric charge. The capacitance of a capacitor can be compared with the size of a water tank: the larger the water tank, the more water it can store.
