Question

(a) Write down the expression for the resistance of a metallic wire in terms of the
resistivity​

Answer 1

Answer:

Answer. Explanation: (a) The ratio between the cross sectional area and length of the conductor is called as resistance (R) where as the ratio between the product of the resistance and its area to the length of the conductor is called as resistivity(ρ). ... Resistance of the metallic wire be R and resistivity be ρ.

Answer 2

Answer:R=resistivity*length/area
