In Thomson's effect we pact with only metallic rod and not with thermocouple as in Peltiers effect and Seebeck's effect. (That's why sometimes it is called as homogeneous thermo electric effect. When a current goes by an unequally heated substance, there is an evolution or absorption of heat in the body of the substance. This is known as Thomson's effect.
Show that the heat transferred during an in nitesimal quasi-static process of an ideal gas can be written as dQ = Cv nR V dP + Cp nR PdV: Apply this equation to an adiabatic proces
In a vacuum tube, electrons accelerate from the cathode element to the plate element, which is maintained at a positive potential with respect to the cathode. If the plate voltage
