T/c is connected in parallel(not always though)as its emf
remain same doesn't matter how mant t/c is connected in
parallel only(note this is not applicable in series connection)

one purpose is the measurement of average temperature
between several locations. The easiest way to do this is to
connect several thermocouples in parallel with each other.
The milli volt signal produced by each thermocouple will
average out at the parallel junction point. The voltage
differences between the junctions drop along the resistances
of the thermocouple wires.
