I can describe how an electric cell works and how electric cells are combined to produce batteries of different voltages.
Muuji qoraalka
Electric cells contain a store of chemicals that react to produce a voltage across two electrical contacts.
An electric cell made of two different metals in contact with an electrolyte, produces a voltage across the metals.
The size of voltage across an electric cell depends on the materials it is made from.
A battery is made of one or more electric cells, which can be connected in series to produce a larger voltage.
The chemical reaction in a rechargeable battery is reversed when an external voltage is connected across it.
