Resistance
Determines how much current flows for a given voltage. Higher resistance means less current flows.
Ohm
The unit of resistance. One ohm allows 1 amp to flow when a voltage f 1 volt is applied.
Conductor
A material with a low electrical resistance. Metals such as copper and aluminum are good conductors.
Insulator
A material with a high electrical resistance. Plastic and rubber are good insulators.
