What happens to the reading on a potentiometer when the resistance of the galvanometer is increased?
Reading increases
Reading decreases
Reading remains the same
Reading becomes zero
Increasing the resistance of the galvanometer reduces the current through it, which can lead to a decrease in the reading on the potentiometer.

Q: What happens to the reading on a potentiometer when the resistance of the galvanometer is increased?
Solution: Increasing the resistance of the galvanometer reduces the current through it, which can lead to a decrease in the reading on the potentiometer.
Steps: 6
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.
