A thermoelectric generator consists of a series of semiconductor elements heated on one side and cooled on the other. It is a type of thermal engine, except that the output is electrical rather than mechanical work. Electric direct current output is produced as a result of an input heat transport of energy. In a particular experiment, the steady state direct current is measured to be 0.500 A and the potential across the unit is 0.800 V. The heat input to the hot side is 5.50 W. Determine the heat transfer rate from the cold side and the energy conversion efficiency of this device.
