Answer / renjith
When the junction of dissimilar metals are kept at different
temperatures,then an emf is introduced b/w both the junction.

Answer / bharathi
Two dissimilar material jointed together it is called hot
junction and kept free other end it is called cold junction.
An emf induced at cold junction it directly proportional to
temperature difference between two junctions. For example
the hot surface is in 300 deg c (hot junction) and room temp
is 30 deg c (cold junction) you will get mv which is equal
to 270 deg c.

Answer / rajesh
when any two dissimilar metals joined at each end ,one
junction at higher temp another at low temp ,then there
induced an emf ,thats depend on differrence between two
junction temperature

Answer / bilawal
when any two metals of different nature joind from both the
ends and then heated from on end the current is being
prodused due to the different value of electron in outer
most shell of the metals.

Answer / prasath
THE TEMPERATURE DIFFERENCE BETWEEN TWO DISSIMILAR METALS ARE JOINED AN EMF IN INDUCED AT THE JUNCTION THIS IS SEEBACK EFFECT.
Is This Answer Correct ? | 1 Yes | 2 No |
Answer / manish kumar tiwari
WHEN TWO DISSIMILAR METALS ARE AT DIFFRENT TEMPRETURE ONE OF
THEM IS HOT AND ANODER COLD COMPARING TO IT AND WHEN THE
TEMPRETURE WILL INCRISE IN HOT END THEN AN E.M.F. WILL
INDUSED IN JUNCTIONOF BOTH METALS AND IT IT WILL BE IN "mv"
Is This Answer Correct ? | 2 Yes | 4 No |
Answer / samira patel (itps)
IF TWO DISSIMILAR METALS ARE JOINED TOGETHER SO AS TO FORM A
CLOSED CIRCUIT ,THERE WILL BE TWO JUNCTION FORMED WHERE THEY
MEET EACH OTHER.ONE OF THE JUNCTION IS CALLED HOT JUNCTION
OR REFERENCE JUNCTION AND ANOTHER JUNCTION IS CALLED COLD
JUNCTION OR MEASURING JUNCTION.IF HOT JUNCTION IS HEATED AN
EMF IS INDUCED AND FLOWS THROUGH THE WIRE ,THAT IS MEASURED
BY A GALVANOMETER OR MULTIMETER.THIS EFFECT IS CALLED
THERMOELECTRIC EFFECT AND THIS IS FIRST OBSERVED IN 1821 BY
SEEBACK SO IT IS ALSO CALLED AS SEEBACK EFFECT.

WHEN BOTH WIRES OF THERMOCOUPLE R SHORTED WHAT IS THE OUTPUT THE TEMP ARE 0,30,250,320
I have installed a RTD whose length is 2250mm(RTD stem length), but it's upper 200 -250mm is out of the reactor, and this upper 200mm stem is surrounded by atmospheric temp. And the lower portion i.e. 2000mm is in contact with the measuring fluid, then does the final measuring temp. Gonna change as the upper 200mm RTD stem is out of reactor?
