Which of the following graphs shows the variation of thermoelectric power with temperature difference between hot and cold junction in thermocouples

Which of the following graphs shows variation between density of water and temperature?

Which of the following graphs represent variations of thermo emf (E) of a thermocouple with temperature t of the junction, the cold junction being kept at 0^(@)C ?

Plot a labelled graph to show variation of thermo-emf .e. versus temperature difference .theta. between the two junctions of a thermocouple. Mark .N. as neutral temperature and I as temperature of inversion. (ii) What is Peltier effect ?

Show, with the help of a labelled graph, how thermo emf .e. developed by a thermocouple varies with theta , the temperature difference between the two junctions. On the graph, mark neutral temperature as theta_(N) and temperature of inversion as theta_(1) .

An emf of 1 V is developed when the temperature difference between the hot and cold junctions of a thermocouple is 100 K. Assuming that the cold junction is heated by 20 K , determine the percentage change in the thermo emf.

In the following thermocouple , the direction of the thermo electric current at the hot junction is from

In a thermocouple, the temperature that does not depend on the temperature of the cold junction is called

Draw the graph showing the variation of current with voltage for a p-n junction diode.
