Input: The increase in this quantity due to high frequency caused by Foucault currents manifests itself as the skin effect. Cooper pairs appear when this quantity goes to zero. The reciprocal of this quantity is measured in siemens, and, when working with AC circuits, it is known as impedance. A circuit consisting of four of its namesake devices with a galvanometer in the middle, known as a Wheatstone Bridge, can be used to measure this quantity. Joule's First Law states that current squared times this is equal to power. For 10 points, name this electrical quantity which, when multiplied by current, yields the voltage drop across its namesake device.
Output:
Science
