1. Which of the following laws is associated with the heating effect of electric current ?Joule's law Ohm's law Faraday's law Newton's law

Identifying the Correct Law

1. Understanding the Laws:

   • Joule's Law: This law states that the heat produced by an electric current passing through a conductor is proportional to the square of the current, the resistance of the conductor, and the time the current flows.
   • Ohm's Law: This law relates voltage, current, and resistance in an electrical circuit (V = IR).
   • Faraday's Law: This law pertains to electromagnetic induction and the relationship between electric circuits and magnetic fields.
   • Newton's Law: This generally refers to laws of motion and gravity, not related to electrical effects.

2. Connection to the Heating Effect:

   • Joule's law explicitly defines the heating effect produced by electric current, while the others deal with different aspects of electricity or motion.

Final Answer

The correct answer is: Joule's law.
