Physics efficiency definition
WebbAn Electric motor is an electro-mechanical device that converts an electrical energy input to mechanical energy output. In DC motors this is achieved primarily through the interaction of a stationary magnetic stator and an electromagnetic rotor producing a force, this is known as the motor effect. Webbefficiency meaning: 1. the quality of achieving the largest amount of useful work using as little energy, fuel, effort…. Learn more.

Did you know?
Efficiency is very often confused with effectiveness. In general, efficiency is a measurable concept, quantitatively determined by the ratio of useful output to total useful input. Effectiveness is the simpler concept of being able to achieve a desired result, which can be expressed quantitatively but does not usually require more complicated mathematics than addition. Efficiency can often be expressed as a percentage of the result that could ideally be expected, fo… WebbDefine Efficiency in terms of Physics.
