Resistance depends on a conductors' length, cross-sectional area, the material it is made of, and its temperature:
- A larger cross-sectional area of a conductor offers less resistance to the charge flow.(If the cross section is doubled, then the resistance goes to half of its original value.)
- A longer conductor has greater resistance than a shorter one. (If length is doubled, then the resistance is also doubled.)
- Generally an increase of temperature of a conductor, usually contributes to an increase in the resistance but not for all substances.
