Production of heat due to an electric current flowing through a conductor is given by _________________?
Correct answer: A. Joule effect
- A. Joule effect
- B. Joule Thomsons effect
- C. Comptons effect
- D. Feed back effect
Explanation
The heating of a conductor by current is called the Joule effect, described by the relation H = I²Rt, where heat is produced because moving charges transfer energy to the conductor. Joule-Thomson effect concerns temperature changes during gas expansion, so students may incorrectly select it because both names contain Joule.

About Steady Current
Steady current is the continuous flow of charge at a constant rate through a conductor. The topic covers current, charge, potential difference, resistance, Ohm's law, resistivity and electrical power, along with series and parallel circuits, while distinguishing conventional current direction from electron motion.
