a) Heat produced is directly proportional to the square of the current passing by a conductor.
b) This effect is produced because of collision of free electrons with positive ions of the current carrying conductor.
c) It is not a reversible effect.
d) Heat produced depends upon resistance (and therefore temperature also) of the conductor.
e) It is mainly a heating effect

1. The probability of dissociation of water into H + and OH - , to a good approximation, can be characterized by the Boltzmann distribution: W ≈ e -Eα/ KT If, at 27°C, 1.
A thermodynamic process, in which the volume of gas always same is known as isochoric process. In this process, the work completed by the body is zero. Therefore from first law
Sir,Do you tell me about 5th state of matter i.e Be condensates
A load of P57 kN is being hoisted at a constant speed by the motor, M which has a weight of 0.5kN. The beam has a weight of P58 N/m. Assume that the hoisting has stopped at the pos
If we permit monochromatic light to fall normally on the surface of lens, then circular interference fringes of radius r can be consider in the reflected light. This circular fring
How long will fiber optics last? In case of glass basically indefinitely the inert characteristics of the material. It refers to the actual fiber, but not to the polymer claddi
This assignment is intended to introduce you to the theory of gas turbine propulsion. The theory of the most simple gas turbine aircraft engine, the ideal turbojet, is detailed in
Start by opening the "Maze Game" activity. When you open it you will be presented with the "Arena of Pain". Set it to "practice" and play with the controls. You will find that by c
In an isothermal process, the temperature of body always same throughout the process. As the internal energy of a system depends only on its temperature, thus there is no modificat
