Question

1. Explain how a battery works

Answers

GPT 3.5
A battery works by converting chemical energy into electrical energy. Inside a battery, there are two electrodes (usually made of different metals) that are immersed in an electrolyte solution. When the battery is connected to an external circuit, a chemical reaction occurs between the electrodes and the electrolyte. This reaction causes a flow of electrons from one electrode to the other, creating a difference in electric potential, or voltage.

As electrons flow from one electrode to the other through the external circuit, electrical energy is generated and can be used to power a device. The flow of electrons continues until the chemical reaction is depleted, at which point the battery is considered "dead" and no longer able to produce electricity.

Rechargeable batteries work in a similar way, but can be reversed by applying an external voltage to the battery, forcing the reaction to run in the opposite direction and recharging the battery for later use.
