Because the flow from amp is AC, not DC as from a battery, you call it impedance. In a DC circuit, where the flow goes only one way, it matches simple resistance: you count it dividing the voltage ...

Potential difference (or voltage) is a measure of energy, per unit of charge, transferred between two points in a circuit. A potential difference of 1 volt means that 1 joule of work is done per ...

Abstract: In order to ensure increasing current rating of semiconductor switches, paralleling is unavoidable. In this paper, the paralleling of switches has been studied from the reliability point of ...
