A coaxial cable has a capacitance of 30 pF/ft and an inductance of 78 nH/ft. What is the characteristic impedance?Inductance, coils, are one way of doing that. A coil, or inductance, impedes, or slows, or stops, AC. So, if you wind a coax cable into a coil you produce some inductance on the "OUTSIDE" of that coax. That inductance slows or stops electrical signals from flowing on the 'outside' of that cable. Which is good, and the whole idea of …0.840c-0.880c. Solid Teflon (ST) 1.46. 0.694c.

More seriously, the equation doesn’t appear to match the one in the source referenced. Equation (7) in chapter 5 of “Inductance Calculations” by F. W. Grover gives the formula for self inductance of a straight conductor as 200 nH/m * L*(log(2*L/r)-0.75) where L is the length in meters, and r is the wire radius in meters.3.
