ELECTRICITY TERMS
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.
if an object has more negetive charges than positive,
than its charge is negetive.
if an object has a same amount of charges ,
than its charge is neutral.
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.
