Chapter 4 EFFICIENCY OF ENERGY CONVERSION
personal.ems.psu.eduEFFICIENCY OF ENERGY CONVERSION 57 Illustration 4-1. An electric motor consumes 100 watts (W) of electricity to obtain 90 watts of mechanical power. Determine its efficiency (E). Solution. Because power is the rate of energy utilization, efficiency can also be expressed as a power ratio. The time units cancel out, and we have Efficiency =
