Resistivity () is the measure of a material's ability to resist the flow of charge through it

 

 

Resistance is a physical property of a circuit element that impedes the flow of charge. It is measured in ohms,

 

The resistance  of a conducting wire of uniform cross-section is a function of its length (), cross-sectional area (), and a material's resistivity ()

 

 

A resistor is a circuit element which models the current-resisting behaviour of a material

Resistors are passive circuits which dissipate power

Ohm's law requires confirming to the passive sign convention (high protentional + to the lower potential -)
