Batteries
A battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices.
Batteries are a collection of one or more cells whose chemical reactions create a flow of electrons in a circuit. All batteries are made up of three basic components: an anode (the ‘-‘ side), a cathode (the ‘+’ side), and some kind of electrolyte (a substance that chemically reacts with the anode and cathode).
