Thermoecuelectric na-ekpochasị usoro ngụkọta:

Tupu ị na-etinye ihe ọkụkụ nke ọma, iji ghọta arụmọrụ ya, n'eziokwu, ọgwụgwụ oyi nke celluer, enwere mmadụ abụọ: otu bụ Joule Heat QJ; Nke ọzọ bụ ihe ọkụ ọkụ QK. A na-ebugharị ihe dị ugbu a site na ihe dị ka nke ihe dị n'ime ahụ na-eme ka a na-emepụta ihe ọkụkụ, a na-ebubata oke ọkụ, a na-ebugharị ọkara nke na-ekpo ọkụ, na-ebugharị ọkara ahụ na njedebe ọkụ njedebe.

Izipụta oyi QC = qπ-QJ-QK

= (2P-2N) .Tc.i-1 / 2j²r-K (tc-tc)

Ebe r na-anọchi anya ngụkọta nke otu na k bụ ngụkọta ọkụ ọkụ.

Okpomoku di egwu site na njedebe na-ekpo ọkụ QH = Qπ + QJ-QK

= (2P-2N) .th.i + 1 / 2I²r-K (TH-TC)

Enwere ike ịhụ ya site na usoro abụọ dị n'elu na ike eletrik bụ ihe dị iche n'etiti okpomọkụ na-ekpo ọkụ site na njedebe na-ekpo ọkụ, nke bụ ụdị "mgbapụta okpomọkụ":

QH-QC = I²r = p

Site na usoro dị n'elu, enwere ike ikwubi na okpomoku QH na-echeputa site na njedebe ọkụ eletrik bụ nha nke ike ntinye na oge mgbụsị oge, ma enwere ike ikwubi ya na Oge oyi QC hà nhata na ọdịiche dị n'etiti okpomoku na-eweta site na njedebe ọkụ na-ekpo ọkụ na ikike nrụpụta.

QH = P + QC

QC = qh-p
