There are two types of electricity;

Static Electricity. ( this is a build up of electrical charge on insulators)

Current electricity. Easily the most important and useful form. This type flows along conductors. Moving currents can produce heat, light + magnetic fields.

How does metallic conduction work

1.5V Cell Cells are cylinders which contain complex mixtures of chemicals. The chemical reactions inside effectively separate + and - charges and produce an electrical current

A battery is a group of cells. Here two 1.5V cells are in series and produce 3V
