A watt is a unit of power, named after engineer James Watt, which measures the rate of energy transfer. A watt, in electrical terms, is the rate at which electrical work is done when one ampere (A) of current flows through one volt (V). Formula:

WebPower within an electrical circuit is only present when BOTH voltage and current are present. For example, in an open-circuit condition, voltage is present but there is no current flow I = 0 (zero), therefore V*0 is 0 so the power dissipated within the circuit must also be 0.Likewise, if we have a short-circuit condition, current flow is present but there is no …
WebSo according to the definition, the electrical power is the rate of flow of electrical energy or the work done on electrical charges in an electrical circuit. The electrical energy is the energy stored in charge Q under the influence of voltage V (potential difference). Hence the electrical power is; P = Electrical Energy / Time = (V x Q) / t.
