Question

You are using your phone, and all of a sudden the battery dies. Many people think that means you have used up all the electricity in the battery. After reading Chapter 8 - Static and Current Electricity do you agree? What does a battery actually do - and how can plugging it in allow it to be used again?

Answer 1

A battery can change chemical energy to electricity by putting certain chemicals in contact with each other in a specific way. Electrons, which are small parts of an atoms, will travel from one kind of chemical to another under the right circumstances. When electrons flow, this makes an electrical current that can power something. After plugging in the battery, it can charged and electric potential of the battery can be restored to the original levels providing it a state of being used again.
