How is current measured
Webcapacitance, property of an electric conductor, or set of conductors, that is measured by the amount of separated electric charge that can be stored on it per unit change in electrical potential. Capacitance also implies an associated storage of electrical energy. If electric charge is transferred between two initially uncharged conductors, both become equally … WebThe electric current is measured in ampere. One ampere of current represents one coulomb of electric charge moving past a specific point in one second. 1 ampere = 1 coulomb / 1 second The conventional direction of an electric current is the direction in which a positive charge would move.
