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.
