Thermometer thermocouple Physics

A thermocouple consists of wires of two different materials, copper and iron ,joined together. When one junction is at a higher temperature than the other an electric current flows and produces a reading on a sensitive voltmeter which depends on the temperature difference between the two junctions (hot junction and the cold junction). A voltmeter can measure the voltage that develops by ...

A thermocouple is a useful device to measure very high temperatures in remote or dangerous locations for example, in a volcano! So the physical property that a thermocouple uses is the temperature difference of a metal and the potential difference (voltage) that this produces.

IGCSE Physics: Thermal Physics Flashcards | Quizlet

In this thermometer, The probe contains 2 different metals joined metals to form 2 junctions. The temperature difference causes a tiny voltage which makes a current flow. A greater temperature difference gives a greater current. Thermocouple thermometers are used for high temperatures which change rapidly and have a large range (200C° to 1100°C)

Jan 14, 2011· The direction of an electromagneticallyinduced current (generated by moving a magnet near a wire or by moving a wire in a magnetic field) will be such as to oppose the motion producing it. This law is named after the German physicist Heinrich Friedrich Lenz (1804–1865), who announced it in 1833. Alternate Current.
