SUMMARY
The resistance of the insulation in a coaxial cable can be calculated using the formula R = ρ(l/A), where ρ is the resistivity, l is the length of the cable, and A is the cross-sectional area between the inner radius 'a' and outer radius 'b'. The area A is determined by the equation A = π(b² - a²). However, for accurate results, integration may be necessary due to the varying area with respect to radius. This approach ensures a precise calculation of resistance across the insulation material.
