Laws of Resistance

The resistance of wire depends upon its length, area of cross-section, type of material, purity and hardness for material of which it is made of and working temperature,
Resistance of wire is
(i)    directly proportional to its length i.e. R l
(ii)    inversely proportional to its area of x-section i.e. R I
  or    R l

  or    R = p   l

where p (rho) is constant depending upon the nature of the material and is known as specific resistance or resistivity of the material.
