Electrical Energy Efficiency

Electrical efficiency - Wikipedia

The efficiency of a system in electronics and electrical engineering is defined as useful power output divided by the total electrical power consumed (a fractional expression), typically denoted by the Greek small letter eta (η – ήτα). $${\displaystyle \mathrm {Efficiency} ={\frac {\mathrm {Useful\ power\ output} }{\mathrm {Total\ power\ input} }}}$$ If energy output and input are expressed in the same units, efficiency is a dimensionless number.
