Batteries to Circuits.

A source of electricity, such as a battery or a generator is used to create chemical energy. The chemical energy produced is used to create voltage (electric potential difference) between the battery and the electrode. The movement of charge from a negative to positive charge, known as a electron flow, occurs in this process. The product of this process is electrical energy, which will then be converted into different forms of energy. This process gets repeated continuously for the same results, which in this case would be to light the lightbulb, as shown on the diagram above.
