Question: What happens to the reading on a potentiometer when the resistance of the galvanometer is increased?

Options:

Correct Answer: Reading decreases

Solution:

Increasing the resistance of the galvanometer reduces the current through it, which can lead to a decrease in the reading on the potentiometer.

What happens to the reading on a potentiometer when the resistance of the galvanometer is increased?

Correct Answer: Reading decreases

Step 1: Understand what a potentiometer is. It is a device used to measure voltage or potential difference.
Step 2: Know that a galvanometer is an instrument that detects and measures small electric currents.
Step 3: Recognize that the galvanometer has a certain resistance, which affects how much current flows through it.
Step 4: When the resistance of the galvanometer is increased, it becomes harder for current to flow through it.
Step 5: With less current flowing through the galvanometer, it may not respond as strongly to the voltage being measured.
Step 6: As a result, the reading on the potentiometer may decrease because it is showing less current or voltage.

Potentiometer Functionality – Understanding how a potentiometer measures voltage and the role of current in its operation.
Galvanometer Resistance – The effect of changing the resistance of the galvanometer on the overall circuit current and readings.
