Answer 2

Answer:

Heating effect of current

Explanation:

resistance can be compared with the force of friction. When you rub your palms against each other your palms become warm due to the friction between the surface of your palms. Similarly, when an electric current passes through a high resistance wire (like nichrom wire), the electrical energy is converted into heat energy which heats up the resistance wire. This is called heating effect of current
