WebThe ratio of power to current at a transducer has a name: potential difference (voltage, V). In symbols, V = P / I This is the same as the ratio of energy E transferred per unit charge Q, or, V = E / Q, since V = P / I = (E/ t ) / (Q/ t ) = E / Q WebIn this section of Lesson 3, we will revisit the concept of power and develop new equations that express power in terms of current, electric potential difference and resistance. New Equations for Power. In Lesson 2, the concept of electrical power was introduced. Electrical power was defined as the rate at which electrical energy is supplied to ...

WebThe unit for power is watts. energy transferred (work done)=potential difference×charge. power=potential difference×current. When an electric current passes through a resistor, some of the electric energy is lost as heat. This is called Joule heating. The power dissipated is given by the following equation: power=(current)^2×resistance WebThis is the opposite to the direction of electron flow, as the conventional current was described before electric current was really understood By definition, conventional current always goes from positive to negative (even through electrons go the other way)
