Resistance there is a resistance [resistance: the degree to which a component impedes the passage of current shown by the letter r the unit of resistance is the ohm] to the flow of an electric current [current: moving electric charges, for example, electrons moving through a metal wire] through most conductors conductor: an electrical. Electric current is electric charge in motion it can take the form of a sudden discharge of static electricity, such as a lightning bolt or a spark between your finger and a ground light switch plate more commonly, though, when we speak of electric current, we mean the more controlled form of. Ohm’s principal discovery was that the amount of electric current it is used so often in the study of electricity how voltage, current, and resistance. In this worksheet, students will learn what electric current and voltage are and how we measure them. Resistance: resistance, in electricity, property of an electric circuit or part of a circuit that transforms electric energy into heat energy in opposing electric current.
