What energy conversion takes place inside a battery when it powers a device?

Explanation

A battery converts stored chemical energy into electrical energy through a chemical reaction between its internal components, producing a flow of electrons through an external circuit. As the battery discharges, its chemical reactants are gradually used up, which is why batteries eventually need to be replaced or recharged. Rechargeable batteries can reverse this chemical reaction when supplied with electrical energy from an external charger. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
