Current, resistance, and resistivity review - Khan Academy

WebResistance (R) is a measure of how difficult it is for current to flow. Resistance is measured in units called ohms (Ω). The amount of. current. flowing in a circuit is affected by the … WebEddy currents in conductors of non-zero resistivity generate heat as well as electromagnetic forces. The heat can be used for induction heating. The electromagnetic forces can be used for levitation, creating movement, or to give a strong braking effect. Eddy currents can also have undesirable effects, for instance power loss in transformers. choopoons stores
