Define electric power and its si unit
WebApr 9, 2024 · Electrical power is measured as the rate of electrical energy which is transferred per unit time in an electrical circuit. It can also be defined as the rate at which, in an electrical circuit, the energy is transformed or the work is done. Its SI Unit is joule per second or watt and is denoted by P. WebThe standard electrical units are defined in a specific order. The ampere is defined first. It is an SI base unit, the only electrical unit derived from the outcome of an experiment. Next up after the ampere comes the coulomb and charge on an electron. Then we derive the … Current is reported as the number of charges per unit time passing through a … In metal wires, current is carried by negatively charged electrons, so the …
