What happens to the reading of a potentiometer if the temperature of the wire increases?
It increases.
It decreases.
It remains constant.
It becomes zero.
Show Solution
Copy
As temperature increases, the resistance of the wire typically increases, which can affect the potential gradient and thus the reading.

Q: What happens to the reading of a potentiometer if the temperature of the wire increases?
Solution:
As temperature increases, the resistance of the wire typically increases, which can affect the potential gradient and thus the reading.
Steps: 6
Show Steps
Step 1: Understand what a potentiometer is. It is a device used to measure voltage or potential difference.
Step 2: Know that a potentiometer has a wire that conducts electricity.
Step 3: Recognize that when the temperature of the wire increases, the atoms in the wire move more and can cause more resistance.
Step 4: Understand that increased resistance means that it is harder for electricity to flow through the wire.
Step 5: Realize that if the resistance increases, the potential gradient (the change in voltage along the wire) can change.
Step 6: Conclude that as the potential gradient changes, the reading on the potentiometer will also change.
