How does a battery work?

Essentials. A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
