Question:
Which of the following quantities does not change when a resistor connected to a battery is heated due to the current?
Which of the following quantities does not change when a resistor connected to a battery is heated due to the current?
Show Hint
Temperature affects motion, not the number of charge carriers.
Updated On: Mar 18, 2026
- Drift speed
- Resistivity
- Resistance
- Number of free electrons
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Heating increases lattice vibrations.
Step 2: Resistivity and resistance increase, drift speed changes.
Step 3: Number of free electrons remains unchanged.
