Explain the heating effect of electric current. Current: The electric current is defined as the charge flowing in a conductor per unit of time. The current is measured in the units of Amperes. One Ampere is equal to one Coulomb per second ...
Explain the heating effect of electric current. Briefly define electric current. Explain what is electric potential and its basic properties. What is definition of electric current? What is the definition of electric current? Describe how the electric current moves through the simple circuit. ...
We show experimentally that the passing of a pulse electric current through a strip of stainless steel with a surface layer containing grinding-induced tensile stresses substantially reduces their level. In this case, the effect of treatment is not related to the macro-heating of the strip metal....
An electric bulb uses the principle of heat generation in the filament due to electricity, and hence no magnetic effect is used. A geyser also uses the heat effect as the heating rod increases in temperature and causes the water surrounding it to boil slowly. The effect of ther...
The possibilities of growth and healing of a pore in metal under the effect of temperatue and concentration gradients are analyzed. It is shown that in pused heating, the temperature gradient in the vicinity of a pore positioned on the surface of the specimen is steeper than the gradient of...
effect of electric current. It works such that when current, more than a particular value is passed through the wire, due to the heating effect of electric current it gets melted. The reason behind the melting of wire is its low melting point. Once this wire g...
The effect of electric current pulse on the casting ZA12 alloy was investigated.The results show that the primary phase in the solidification structure with electric current treatment evolves into near spherical fine particle from normal dendrite and the tensile strength is improved.The accelerated part...
As the temperature further deviates, consumers may shift to other heating appliances such as heat pumps, electric heaters, etc., and thus the Energy Star air conditioners become less competitive. Fig. 1: The effect of temperature on Energy Star air conditioner purchase. a Full sample (N =...
bar- a heating element in an electric fire; "an electric fire with three bars" burner- the heating elements of a stove or range on which pots and pans are placed for cooking; "the electric range had one large burner and three smaller one" ...
It is shown that a continuous electric current, which is several orders of magnitude lower than the peak current in the return stroke, is capable of maintaining the channel conductivity. This effect cannot be explained merely by Joule heating but is largely governed by the fact that the ...
