Question

what is heating effect of current tell the answer in a note

Answer 1

Hy.

Electric current is actually the flow of electrons in the conducting material. Now, when these electrons flow, they encounter some resistance in the structure of the conductor, which accounts for the "resistance" of materials. As the electrons collide or vibrate, heat energy is generated depending on the resistance of the conductor. This overall effect is called heating effect of electrical current.

Answer 2

hey dear here is your answer

heating effect of electric current-

we know that when we switch on an electric heater or an electric bulb, it becomes hot. this shows that when electric current flows through the conductor heat is produced in it..

let us see how electrical energy converted into heat energy.......

we know, a metallic conductor contains large number of free electrons.
these electrons move randomly in conductor. when the conductor is connected to the source of electricity like a dry cell, the free electrons begin to drift from negative terminal to positive terminal of the cell through the conductor.. but the motion of free electrons is not smooth.. they collide with atoms and ions of the conductor. As a result of these collisions the kinetic energy of free electrons is transferred to the atoms or ions of the conductor. so the atoms or ions vibrate with large amplitudes about their mean position.. hence, the average kinetic energy or total energy of the ions increases..
the increase in energy of ions increases the temperature of the conductor.
thus, heat is produced when electric current flows through the conductor..
