Question 3(vi)

A current flows through a metallic conductor for a long period of time. State the change you would expect in its:

(a) Resistance

(b) Resistivity

Answer

(a) As current flows for a long period of time, heat is generated and temperature increases. So, the resistance of metallic wire increases as resistance is directly proportional to the temperature of a conductor.

(b) As temperature increases, resistivity of metallic wire increases.
