Does anyone know (or can point me to an explanation) of how the 2nd law
applies to electric motors and generators?
I think I understand how the 2nd law applies to heat engines and I have
an elementary understanding of entropy as it relates to chemical
reactions. These applications explain why heat engines and fuel cell
efficiencies cannot be 100%. I assume the 2nd law applies somehow to
motors and generators but how do you find the theoretical limit for
them? (I know this is quite high since electric motors with 95%
efficiency are already available.)
