1

Capacitor

It is the device that has a capacity to store electric charge

New cards
2

Capacitor

It is made up of two conducting objects placed nearby each other but connected

New cards
3

electrical energy

Capacitor is like a battery, they both store ?

New cards
4

Battery

inside a ?, chemical reactions make electrons move on one terminal and then absorb electrons on the other

New cards
5

Capacitor

This does not make electrons move, it just store them

New cards
6

Capacitance

It is the ability of a capacitor to store an electric charge per unit of voltage across its place of a capacitor
