ABSTRACT
Note that transducers mostly come in pairs, the one being, in effect, the inverse conversion of the other, except that in each case some of the energy is dissipated in the form of heat loss. Thus, for example, we use a flow of water or steam in a turbine to rotate a generator that converts some of that mechanical (flow) energy into electricity, which is then transmitted to a site, such as one's home, where some of it is used to run motors (in fans, vacuum cleaners, turntables, etc.) that once again provide mechanical power. In both conversions, heat is also generated and lost.
