Phonon-drag thermopower quenching in metallic point contacts of size smaller than electron–phonon relaxation length is investigated. This effect makes it possible to measure the absolute value of phonon-drag thermopower in bulk metals in a circuit formed by similar metals by point-contact technique. The asymmetry in heat release at contact sides upon a passage of current and the “ballistic Peltier effect” associated with it and consisting in the emergence of a temperature difference depending on current in a circuit made of a single metal are calculated.
