ELECTRICITY TERMS
Electricity is an essential form of energy derived from the movement of tiny particles within atoms. Atoms, composed of smaller particles with positive and negative charges, usually remain neutral when these charges balance out.

ELECTRICITY TERMS Static Electricity The greeks discovered static electricity by 600 BC. Static electricity is a build up of electric charge in a
object. it is caused by the presence of many particles of the same charge. Static elecricity is an exess of electrical charges trapped on the surface of the object. Circuits For a circuit to work,all its part must be connected. All circuits have 3 main components: A power source such as a battery or a generater. wires that carry the current through the circuit A device such as a bulb or motor electrical charges if an object has more positive charges than negetive,
than its charge is positive. Current Electricity Current electricity is the steady flow of electrons between
objects or places Current electricity is the kind of electricity that powers appliances in your home. Series and Parrellel Circuits Parrellel circuit In a parellel circuit,electricity has
more than one way to go Series circuit In a series circuit, electricity only has one way to go. ELECTRICITY Each atom is made up of a number of even smaller particles. form of energy that is created by the movements of the tiny particles that make up atoms. everything is made of atoms. In an atom, the negetive and positive charges cancel each other out, so the whole atom is neutral.
