Conductor
Material that allows electricity to flow through it freely
A non-conductor/ insulator
Material that doesn't allow electricity to flow through it freely
Resistance
measure of how difficult it is for electricity to flow through a material
Low resistance
good conductors have low resistance
High Resistance
good non-conductors or insulators have high resistance
Metals-
-are good conductors of electricity
Copper-
-is the best inexpensive type of a metal conductor
Silver-
-is an expensive good conductor
Iron-
-is a poor conductor
Non-Metal insulators
glass, wood, plastic, and rubber
Electricity-
-flows freely through a good conductor
Electricity does not-
-flow freely through a non-conductor or insulator
Series circuit
when all the parts of a circuit are connected
In a series circuit when one bulb is out-
-the other bulbs will go out
Parallel circuit
electrical circuit with more than one path
In a parallel circuit if one bulb goes out-
-the other bulbs will stay lit
Home circuits
are set up as parallel circuits
