Question

The resistance R of a wire (in ohms) is given by

Answer 1

Given

The resistance R of a wire​ (in ohms) is given by

`R=(KL)/(d^2)`

L is 1830 feet, d is 169 mils or inch and K is 10.7 ohms.

Explanation

The resistance is given by

`R=(KL)/(d^2)`

Convert inch into feet,

1 inch =0.08333 feet.

169 inch=14.0833feetSubstitute the values,

`\begin{gathered} R=(10.7*1830)/(14.0833^2) \\ R=98.724 \end{gathered}`

Answer

Hence the resistance is determined as 98.724 ohms.
