The impedance of the coax is a relationship of the capacitance per unit length and the inductance per unit length. This tool will help you find the inductance for a given length of coax cable. Coax Inductance Description. The inductance of a coax cable can be useful ... Aug 5, 2020 · Examine the capacitance of Twisted Pairs (2 wires) versus capacitance of a Coaxial Cable (a wire inside a tube). A wire does have very high capacitance reactance as it interacts with stored charges in its surroundings. As you try to send a signal from A to B, a wire in isolation requires the lowest amount of charge.
