a) Thomson's heat is proportional to the current passing by the conductor.
b) This effect is produced when parts of similar conductor are kept at dissimilar temperature.
c) It is a reversible effect.
d) This effect depends upon nature of conductor and temperature difference of dissimilar parts of the conductor.
e) It is heating as well as cooling effect.
