A circuit that skips a resistor is called a:
Type of electricity caused by a build up of electrons in one place
Something that resists or slows down the flow of electricity

A circuit with no breaks in it
What are the names for the three particles in an atom?
Protons Neutrons Electrons
A circuit in which the resistors are on separate paths
A material that carries an electrical current
Type of charge an object will have if it loses some electrons
A device used to prevent the flow of too much electricity
fuse Or circuit breaker
What does the atomic number on the periodic chart tell us about the atom?
The number of protons in the nucleus (also number of electrons if the atom is neutrally charged )
Type of electricity in which charges move in conductors
attract circuit When two objects are pulled together.
attract When two objects are pulled together circuit.

Brought to you by Barr/Batten. Does your clock radio wake you in the morning? The source of electrical energy lies in the forces between electric.
Electricity Active Physics. The Atom All matter is made up of atoms Atoms are made up of 3 types of particles protons, electrons and neutrons Protons.
DATE: TOPIC: ELECTRICITY AND MAGNETISM OBJECTIVE: To establish how electric charges and magnets work.
Electricity and Magnetism By: Victoria. Atom A atom has 3 main parts that are proton, neutron, and electron. there is also a nucleus and a electron cloud.
