Question

what do you mean by heating effect of current name two appliances which work on the heating effect of current explain it

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. Thiseffect is called as heating effect of electric current and it is effectively utilized in heater,electric iron, electric toaster, etc.

Answer 2

when current flows through  a conductor ,it produces heat . this is heating effect of current

electric iron
it has a heating coil inside made up of (nichrome).when current flos thorugh the conductor it  gets heated and becomes red hot and produces heat

ellctric bulb
it consists of a filament made up of tungsten .when electrcity flows through the filament it becomes white hot.the hotness is enough to produce light
