(a) Name two factors on which the specific resistance of a wire depends? (b) Two wires A and B are made of copper. The wire A is long and thin while the wire B is Short and thick. Which will have more specific resistance?

(a) A wire’s particular resistance is determined by two elements.

I The substance’s material and

(ii) The substance’s temperature

(a) Because the specific resistance of a wire is determined by its material rather than its size, both wires will have the same specific resistance.
