The correct answer is A. thermocouple.
A thermocouple is a device that converts thermal energy to electrical energy. It is made of two dissimilar metals that are joined together at one end. When the two metals are heated, an electric current is generated. The amount of current generated is proportional to the temperature difference between the two metals.
Thermocouples are used in a variety of applications, including temperature measurement, temperature control, and power generation.
B. Solar cells convert light energy to electrical energy.
C. Chemical cells convert chemical energy to electrical energy.
D. Piezoelectric devices convert mechanical energy to electrical energy.
E. None of the above.
