Supercapacitors vs. Batteries: What''s the Difference?

A capacitor stores electricity as a static electric field. This is the same thing that happens when you walk across a carpet in socks and build up an electric charge, only to discharge it when you touch a door handle. That just means that supercapacitors can store a much larger electric field than regular capacitors. In this diagram, you

IPhone charging with Supercapacitor

$begingroup$ Capacitors store energy. They''re charged by the force of the voltage being applied to them, meaning an 8 V cap will only charge to 4 V if only 4 V is applied. So no, your 5V 3000 F capacitor does not contain enough energy to fully charge an empty iPhone battery. There''s nearly twice as much energy in a charged 3000F, 5V

Does a capacitor store voltage?

I''m a bit confused about capacitors. I understand they store energy in a field by accumulating opposite charges on the different plates. So a 1 farad capacitor will store 1 coulomb of charge if subjected to 1 volt if I understand the math right. 1 coulomb is also 1 amp-second, so this capacitor can supply 1 amp of current for 1 second.
