Cause of heat production in a current-carrying conductor is
Correct answer: C. Collision of free electrons with atoms or ions of conductor
- A. Collisions of free electrons with one another
- B. High drift speed of free electrons
- C. Collision of free electrons with atoms or ions of conductor
- D. High resistance value
Explanation
Correct. Heat is produced due to collisions of free electrons with atoms or ions in the conductorIn summary, the correct option is **c. Collision of free electrons with atoms or ions of conductor** for the cause of heat production

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
