(adsbygoogle = window.adsbygoogle || []).push({}); This is a suggested relationship between L/R and L

L/R = kl + A/P

P is the resistivity, A is the cross-sectional area and k is the constant for the circuit

Using the value of the y-intercept find a value for P with the appropriate unit

The graph of L/R against L had the intercept of 9 but I have no idea where that fits in. All I know is the answer must be in Ohms

How do I calculate P?

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
