In a potentiometer experiment, if the known voltage is increased, what happens to the balance point?
Correct Answer: Balance point moves towards the positive terminal.
- Step 1: Understand what a potentiometer does. It measures voltage by comparing it to a known voltage.
- Step 2: Identify the known voltage in the experiment. This is the voltage you are adjusting.
- Step 3: Recognize that increasing the known voltage means you are making it stronger.
- Step 4: Realize that to balance the stronger voltage, you need more length of wire in the potentiometer.
- Step 5: Conclude that as you increase the known voltage, the balance point will move towards the positive terminal of the battery.
