What do you mean by the heating effect of electric current? Explain the production of heat in a resistor by the flow of electric current through it. Name two devices based on the heating effect of current.

(N/A) The heating effect of electric current is the phenomenon where heat is generated in a conductor when an electric current passes through it.
When an electric current flows through a resistor,the electrons move through the conductor and collide with the atoms or ions of the resistor. During these collisions,the kinetic energy of the electrons is transferred to the atoms of the resistor,causing them to vibrate more vigorously. This increase in the vibrational energy of the atoms manifests as an increase in the temperature of the resistor,resulting in the production of heat.
Two devices based on the heating effect of electric current are:
$(i)$ Electric iron
$(ii)$ Electric geyser
