What is a wire?
500
The quality of an electric circuit that opposes the flow of current through it.
What is resistance?
500
The force behind electrons that moves them along the conductor and results in current.
What is voltage?
500
Defined as Force times Distance.
What is work?
500
A material having relatively high resistance at room temperature whose electrical characteristics can be changed and controlled by various techniques (such as by adding other elements called “impurities”).
