Energy efficiency in science
WebEfficiency can be determined quantitatively by the ratio of useful output to total input. The ratio of energy transferred to a useful form compared to the total energy supplied initially is called the efficiency of the device. Efficiency is denoted by η. Efficiency formula regarding Work is given as. η = Work output Work input × 100 %.
