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.
The conductivity of an extrinsic semiconductor (A) Decreases with temperature. (B) Increases with temperature. (C) Remains constant with temperature. (D) Decrea
An object starts from point A and moves with constant acceleration in a straight line. 5 seconds after the start, it crosses point B, and 7 seconds after the start it crosses poin
