when 2 different cpnducting materials r brought together and given a supply, there exist a potential difference between the 2.since these are 2 differt materials and an emf will be induced which is called thermo emf

∙ 12y agowhen the two ends of conductor are at different temperature then, a small quantity of current is flow ,because at the high temperature end, the heat energy is able to excit the electron that's called "SEE BACK effect" so the excited electron is free and easily move to the other end.shortly we say that a small voltage difference is created which is called thermal emf.

How are emf measured?
emf in volts
Does motional emf call induced emf?
yes indused emf is also called motional emf. If an open coil is subjected to a variable magnetic field, at the ends of the coil a potential difference is induced which is called induced emf. If a coil is connected to an emf source and switched on, the rising current will produced an variable magnetic field which in turn produces an emf. It is called back emf.
While discharging which is greater TPD or EMF?
EMF is greater

Why emf of battery driving potentiometer is greater than emf of the cell to be measured?
Bcoz the emf which is to be measured is less than emf of driving cell....
