Question

Give an activity to demonstrate joules heating effect with circuit diagram​

Answer 1

Explanation:

When an electric field is applied across the ends of a conductor, the free electrons starts moving towards the electric field. These electrons suffers collision with the atoms which have lost electrons. Due to the collision, energy is transferred to the atoms and they vibrate as they gain energy due to which heat is developed in the conductor. The more is the current, the more will be heat. This is Joule’s heating effect.
