The resistance of a conductor depends onthe cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to note that electrical conductivity and resistivity are inversely proportional, meaning that the more conductive something is the less resistive it is...

A. Conductors have a higher resistance than insulators. B. Conductors allow the flow of electric current, while insulators do not. C. Insulators have a higher resistance than conductors. D. Conductors are made of metals, while insulators are not. ...
Resistivity is the electrical resistance of a conducting material per unit length. In other words, it is the degree to which a conductor opposes the flow of electricity through itself, instead allowing the energy to flow out of the electrical circuit, most often as heat. Resistivity is useful ...
