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 WebOct 19, 2024 · In electrical engineering, electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. Impedance extends the concept of resistance to alternating current (AC) circuits. Impedance possesses both magnitude and phase, unlike resistance, which has only magnitude.
