How does a capacitor work?

In: Technology

A capacitor is two conductors seperated by a thin insulator. The conductors are close enough to interact but not enough to transfer electricity. This allows charge to build up on one of the conductors. The charge can then be dissipated all at once by completing the circuit. The capacity depends on the size/ammount of electrolyte used as an insulator and the size of the conductors.

Followup question, why can’t we use a large capacity, capacitor instead of battery in things like phone, our car, etc?
