In the year 1821, German Physicist namely ‘Thomas Seebeck noticed various thermoelectric effect properties. He noticed that an electrical circuit with two dissimilar metals with different temperatures created an EMF at their junctions. Thomas Seebeck observed that the compass needle deflected when he created a closed loop between two different metals, forming a thermocouple. The circuit generates a current known as the thermoelectric current. Previously, … [Read more...]
