Question: What happens to the reading of a potentiometer if the resistance of the wire increases?

Options:

Correct Answer: Reading remains the same

Solution:

The reading of a potentiometer is independent of the resistance of the wire as long as the potential difference remains constant.

Correct Answer: Reading remains the same

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 with a uniform resistance along its length.
Step 3: Recognize that the reading on the potentiometer shows the voltage across a certain length of the wire.
Step 4: Realize that the reading depends on the potential difference (voltage) applied across the entire wire.
Step 5: Learn that if the resistance of the wire increases, it does not change the total potential difference applied.
Step 6: Conclude that as long as the potential difference remains constant, the reading of the potentiometer will not change.

Potentiometer Functionality – A potentiometer measures voltage and is designed to provide a constant potential difference across its terminals, making its reading independent of the resistance of the connecting wire.
