Question

    Conversion of heat into electrical er is achieved by

    using –
    A Ammeter Correct Answer Incorrect Answer
    B Hydrometer Correct Answer Incorrect Answer
    C Voltmeter Correct Answer Incorrect Answer
    D Thermocouple Correct Answer Incorrect Answer

    Solution

    Thermoelectric generators convert thermal energy into electricity by using heat from the body — or any object with a temperature gradient — as their energy source. At the heart of every thermoelectric generator is an array of thermocouples that are responsible for converting thermal energy into electricity. Bismuth telluride and its alloys are commonly used in thermocouples.
