Homework Statement
Determine the resistance of the insulation in a length l of coaxial cable.inner radius = a and outer radius= b.
Homework Equations
R=[itex]\rho[/itex][itex]\frac{l}{A}[/itex]
Area= [itex]\pi[/itex] [itex] (b^2 - a^2) [/itex]
The Attempt at a Solution
I calculated the area between the two concentric 'circle' with radius 'a' and 'b'.
Then I calculated R using the formula.
However I am not sure whether it is correct approach or not
