To determine the wattage, use a simple multiplication … WebEnergy efficiency is defined as the ratio of the output energy divided by the input energy: η = 100% ⋅ E out / E in. η is the efficiency in percent (%). E in is the input energy consumed in joule (J). E out is the output energy or actual work in joule (J). Example. Light bulb has input power consumption of 50 watts.
Web26 mrt. 2016 · In physics, you can calculate power based on force and speed. Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel: where s is the distance traveled. However, the object’s speed, v, is just s divided by t, so the equation breaks down to.
