What is heating effect of current |
|
Answer» \tWhen electric current passes through a high resistance wire, the wire becomes and produces heat. This is called heating effect of current.\tThis phenomenon occurs because electrical energy is gets transformed into heat energy when current flows through a wire of some resistance say R Ω. For more information refer peda.net (website) it has various numericals also. The factors on which heating effect of electric current depends are 1. Resistance of the condutor 2. For how much time the current rest in that conductor 3.The amount of electric current passes through it. When electricity flows in a conductor than heat energy is generated this effect of electric corrent is called heating effect of electric current. |
