How Do You Calculate the Capacitance of a Coaxial Cable with Polystyrene?

Click For Summary
SUMMARY

The capacitance per meter of a coaxial cable with an inner radius of 0.10 mm and an outer radius of 0.60 mm filled with polystyrene can be calculated using the formula for a cylindrical capacitor. The dielectric constant (kappa) for polystyrene is 2.6. This calculation is essential for understanding the electrical properties of transmission lines. Utilizing resources like HyperPhysics can provide additional insights into the underlying physics.

A coaxial cable used in a transmission line has an inner radius of 0.10 mm and an outer radius of 0.60 mm. Calculate the capacitance per meter for the cable. Assume that the space between the conductors is filled with polystyrene. Kappa for polystyrene is 2.6

I have no clue how to start or what to even think about so any starting point would be greatly appreciated!
