Question

question 5 (1 point) the resistance of wire in milliohms is given by the equation r = ρl/a where r is the resistance in milliohms, ρ is the resistivity of the wire material, l is the length of the wire, and a is the cross - sectional area of the wire. find the wire resistance when the resistivity is 0.762 ω*m, the wire length is 40.84 in, and the cross - sectional area of the wire is 0.018 in². round to the nearest thousandth of a milliohm. your answer: answer

Explanation:

Step1: Identify given values

$
ho = 0.762\ \Omega\cdot in$, $L = 40.84\ in$, $A=0.018\ in^{2}$

Step2: Substitute values into resistance formula

$R=\frac{
ho L}{A}=\frac{0.762\times40.84}{0.018}$

Step3: Calculate the value of R

$R=\frac{0.762\times40.84}{0.018}=\frac{31.11008}{0.018}\approx1728.337778$

Step4: Round to the nearest thousandth of a milliohm

$R\approx1728.338$ milliohms

Answer:

$1728.338$
