Battery - GCSE Physics Definition

Reviewed by: Philippa Platt

Published

In the context of GCSE Physics, a battery is a device that converts chemical energy into electrical energy, providing a source of power for electrical circuits.

It consists of one or more cells, each containing a positive terminal (cathode) and a negative terminal (anode), with an electrolyte that facilitates the flow of charged particles. When connected in a circuit, a battery drives an electric current by allowing electrons to flow from the anode to the cathode, thus powering various electronic devices.

Batteries are essential in everyday life for supplying portable energy to gadgets like mobile phones, remote controls, and torches.
