The device, which converts heat energy into electrical energy is called
Correct answer: A. Thermo couple
- A. Thermo couple
- B. Photo voltaic cell
- C. Thermistor
- D. Thermostat
Explanation
Thermocouples utilize the Seebeck effect to generate a voltage when there is a temperature difference between two different metals. This voltage can then be used to produce electrical energy from heat.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
