SUMMARY
The capacitance per unit length for a coaxial cable can be calculated using the formula C = (2πε) / ln(b/a), where ε is the permittivity of the dielectric material, b is the outer radius, and a is the inner radius. In this case, with an inner radius of 2.0mm, an outer radius of 4.0mm, and a dielectric constant of 2.3 for polyethylene, the capacitance per unit length is determined to be approximately 33.5 nF/m. This calculation is essential for setting up a home video studio, ensuring optimal performance of the video equipment.
