Here are the correct statements about the thermocouple: | Statement | Tick () | | :------------------------------------------------- | :------------------ | | Meter Z measures energy. | | | Meter Z measures potential difference. | | | Meter Z measures power. | | | Materials X and Y are different materials. | | | Materials X and Y are the same materials. | | | Materials X and Y are electrical conductors. | | | Materials X and Y are electrical insulators. | | Explanation: A thermocouple works on the principle that a temperature difference between two junctions made of different electrical conductors generates a potential difference* (voltage). Meter Z is used to measure this generated potential difference. Therefore, the materials X and Y must be different and they must be electrical conductors*. Drop the next question.
