Ha ho na le li-conductors tse peli tse fapaneng kapa li-semiconductors A le B ho etsa loop, 'me lipheletso tse peli li hokahane, ha feela mocheso oa mahlakoreng a mabeli a fapane, mocheso oa ntlha e' ngoe ke T, e bitsoang T. ho sebetsa qetellong kapa qetellong e chesang, 'me mocheso oa pheletsong e' ngoe ke T0 , e bitsoang pheletso ea mahala (eo hape e bitsoang pheletso ea litšupiso) kapa pheletso e batang, matla a electromotive a tla hlahisoa ka loop, le tataiso le boholo ba matla a electromotive a amana le thepa ea mokhanni le mocheso oa lihlopha tse peli. Ketsahalo ena e bitsoa "thermoelectric effect", 'me loop e entsoeng ka li-conductor tse peli e bitsoa "thermocouple".

Matla a thermoelectromotive a na le likarolo tse peli, karolo e le 'ngoe ke matla a ho kopana a electromotive a li-conductors tse peli,' me karolo e 'ngoe ke matla a thermoelectric electromotive a mokhanni a le mong.

Boholo ba matla a thermoelectromotive ka har'a loop ea thermocouple bo amana feela le thepa ea conductor e kopanyang thermocouple le mocheso oa lihlopha tse peli, 'me ha ho letho le amanang le sebōpeho le boholo ba thermocouple. Ha lisebelisoa tse peli tsa li-electrode tsa thermocouple li tsitsitse, matla a thermoelectromotive ke lithempereichara tse peli tsa mateano t le t0. mosebetsi o fokola.
