Electricity & Materials What is a CONDUCTOR?
Electricity & Materials A conductor is a type of material that EASILY allows electricity to flow through it. (Usually a METAL)
Electricity & Materials What is an INSULATOR?
Electricity & Materials An insulator is a material that DOES NOT ALLOW electricity to flow through it. (usually a plastic or rubber)
Electricity & Materials The path taken by an electric current is known as what?
Electricity & Materials A Circuit
Electricity & Materials What three things must a circuit have to work?
Electricity & Materials • An energy source (battery) 2. Wire so the current can move. 3. Something to use the electricity. (Light Bulb)
Electricity & Materials What is a closed circuit?
Electricity & Materials A circuit that can work. (It allows the movement of electricity)
Electricity & Materials What is an open circuit?
Electricity & Materials It is a circuit that is “broken” or not complete, so the electricity cannot travel completely through.
Electricity & Materials What is a SERIES circuit?
Electricity & Materials It is a circuit where the electricity only has one path to follow.
Electricity & Materials What is a parallel circuit?
Electricity & Materials A type of circuit where the electricity has more than one path to follow.
Electricity & Materials In a magnet, where is the magnetic force the greatest?
Electricity & Materials Around the poles (top and bottom)
