WebAug 5, 2024 · 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. On the other hand, a wire over a sheet of metal (a plane), requires MORE charge but will be faster. Share Cite Follow WebMay 16, 2016 · If the load is a pure reactance, the voltage across it is 90° out of phase with the current. However, if the wire is a pure resistance, then the voltage across it must be in-phase with the current.
