The electrical resistance of a wire, or other component of a circuit, is a measurement which identifies how difficult it is for electrical current to flow through it.


The electrical resistance of any given wire decreases with decreasing temperature, and with increasing cross-sectional area, whereas it increases with heat, length and with the amount of impurities in the metal.


So, the most current will flow through a short, fat, cylindrical wire made of a pure form of the metal, in cold conditions!


Electrical resistance is measured in Ohms.
