Question

How does the resistance of conductor depend on:
(a) length of the contuctor?
(b) area of cross -section of hte conductor?
(c) temperature of the conductor

Answer 1

$R=p\frac{L}{A}$

a) Resistance of a conductor directly depends upon length of the wire. (L)
b) It is inversely depends upon area of cross section of the conductor. (1/A)
c) Resistance of a conductor directly depends upon the temperature. (p)
