In a Copper-Iron thermocouple the thermoelectric current flows from

A thermo couple is formed by two metals X and Y metal X comes earlier to Y in Seebeck series. If temperature of hot junction increases beyond the temperature of inversion. Then direction of current in thermocouple will so

The potential difference across 7Omega resistor is equal to_________and the current flowing through the battery is equal to_________ (b) The equivalent resistance across A and Bis equal to__________

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

The trend in the hydrides from Bi to N is

Group 15 of the periodic table consists of the elements N, P, As, Sb and Bi. On passing from N to Bi, the oxides of the elements of general formula M_2 O_3 become
