Electricity is a branch of Physics that concerns the properties and movement of electrically charged particles. When the charged particles are on the surface of a material, it is called Static Electricity. When the charges move through wires, it can be AC or DC Electricity.
Electricity and Magnetism are interrelated. Movement of electrical charges creates magnetic fields, while changes in magnetic fields can create electricity.
Knowledge of electricty is important in learning how electrical devices work.
