Conductors and Insulators
conductor
A material that allows an electric charge to pass through it easily.
insulator
A material that allows an electric charge to pass through it easily is called a conductor.
Resistance
resistance
The property of a material that determines how easily a charge can move through it.
ohms
Electrical resistance is measured in units called ohms.
Superconductors
Grounding
Grounding
