when current is passed by a junction of two dissimilar solids the temperature is either evolved or absorbed at the node this effect is known as
the rate of modification of thermo emf with the change in the temperature of the hot junction is known as thermoelectric
when the two junctions of a thermo couple are maintained at dissimilar temperatures then a light begins going through the loop called as thermo
if two lines of dissimilar metals are connected at their ends so as to form two junctions then the resulting arrangement is known as a thermo
a secondary cell is that cell is which the electrical energy is first up as a chemical energy and when the current is taken from the battery the
