# How do you calculate Thomas coefficient and Seebeck coefficient?

Wed April 06, 2011

Dear student

If the temperature difference ÎT between the two ends of a material is small, then the thermopower of a material is conventionally (though only approximately, see below) defined as:



where ÎV is the thermoelectric voltage seen at the terminals. (See below for more on the signs of ÎV and ÎT.)

This can also be written in relation to the electric field E and the temperature gradient , by the equation:


Hope this helps.

# A cell of emf E and internal resistance r is connected to two external resistance R1 and R2 and a perfect ammeter.The current in the circuit is measured in four different situation: (i)without any external resistance in the circuit (ii)with resistance R1 only (iii)with Ri and R2 in series combination (iv)with R1 and R2 in parallel combination The currents measured in the four cases are 0.42A,1.05A,1.4A and 4.2A,but not necessarily in that order.Identify the currents corresponding to the four cases mentioned above.
