GCSE Physics

Resistance Summary

Resistance depends on the type of material - metals have the lowest resistance.

GCSE Physics

The longer a conductor, the greater its resistance. Specifically, resistance is directly proportional to length.
R is directly proportional to l

GCSE Physics

The fatter a conductor, the lower its resistance. Specifically, resistance is inversely proportional to cross-sectional area.
R directly proportional to 1/A
