Question

define heating effect of current ?

Answer 1

If an electric circuit is purely resistive (only resistors are connected to a battery), the energy from the source continually gets dissipated totally in the form of heat. This effect is called as heating effect of electric current and it is effectively utilized in heater, electric iron, electric toaster, etc.


or


The heat produced when an electric current passes through a material, due to resistance. A certain portion of the electrical energy passing through a conductor is converted into heat energy due to the resistance of said conductor. Also called heating effect of a current, or Joule effect

Answer 2

when we pass current through any conductor, after sometime it automatically gets heated & this is actually the heating effect of current. Fuse works on the principle of heating effect of current, when a large amount of current is passed through it, it gets heated and melts.

hope it helped
