Question

Determine the resistance of a conductor having 1 mm 2 cross sectional area and 15 m long. The specific resistance of the conductor material is 1.75 10 m. ×

Answer 1

Answer:

Explanation:

The Resistance of the Conductor is 2610 Ohms

Given, The cross-sectional area of conductor (A) = 1mm  

                                                                                    = ${1}\times{10^-^2}$

And We know that the Resistance of a conductor is directly proportional to the product of Length of conductor and the Resistivity of the conductor but inversely [proportional to the cross-sectional area of the conductor.

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

   =$\frac {1.74\times15}{0.01}$

   = 2610 ohms

hence, the Resistance of the Conductor is 2610 Ohms
