Question

Two similar thermocouples made up of similar metals A and B are
connected through a key K and sensitive galvanometer G as shown in
the figure. One of the thermocouple is dipped in a hot bath maintained
at temperature t₂ and other one in a cold bath at a temperature t₁. When
the key K is pressed a deflection is seen in the galvanometer because :
(a) an emf of the order a few of microvolt is generated which is
proportional to (t₂ – t₁ )
(b) an emf is generated the value of which will depend upon the
temperature of the hot bath only
(c) an emf of about 1 volt is generated which will be proportional
to (t₂ – t₁ )
(d) an emf of a few microvolt is generated which will be proportional
to t₂ only
