- Introduction
When two different metallic strips are joined together and heated to the same temperature, a phenomenon known as thermoelectric effect occurs. This effect is used in various applications in the field of thermoelectricity.
- Explanation

Thermoelectric Effect: When two different metals are joined together to form a circuit and heated to the same temperature, a potential difference is generated between the two junctions. This potential difference can be used to create an electric current, which is known as the thermoelectric effect.

Applications: This kind of arrangement is used in thermocouples, which are widely used for temperature measurement in various industries. Thermocouples are made by joining two different metallic strips at one end to form a junction. When this junction is heated, a voltage is generated which is proportional to the temperature difference between the hot junction and the cold junction.

Types of Thermocouples: There are different types of thermocouples based on the combination of metals used, such as Type J (iron-constantan), Type K (chromel-alumel), Type T (copper-constantan), etc. Each type has its own temperature range and sensitivity.

Advantages: Thermocouples are widely used because of their simplicity, low cost, and wide temperature range. They can measure temperatures ranging from -200°C to 2300°C.
- Conclusion
In conclusion, the thermoelectric effect is a useful phenomenon that is utilized in thermocouples for temperature measurement. By joining two different metallic strips and heating them to the same temperature, a potential difference can be generated, which can be used to measure temperature accurately in various industrial applications.
