Question

What is the conductor's resistance if its length is 2m and has a cross-sectional area of 0.7m with a resistivity of4Ωm? a. 1.4 Ω b. 0.08 2 11.42 Ω d. 0.35 c.

Answer 1

Answer:

The answer is c. 11.42 Ohm

Explanation:

The conductor's resistance is calculated by the formula in the figure.

So, you have to replace the given values into the formula.

Resistance of a conductor is equal to the product of rho by the lengh of the conductor divided the cross-sectional area of the conductor.

$R= 4 ohm.m . (2m/o.7m^{2} )\\R=11.42ohm$
