In a potentiometer experiment, if the known voltage is increased, what happens to the balance point?
It moves towards the positive terminal.
It moves towards the negative terminal.
It remains unchanged.
It becomes unstable.
Increasing the known voltage will cause the balance point to move towards the positive terminal, as a higher voltage requires a longer length of wire to balance.

Q
Q: In a potentiometer experiment, if the known voltage is increased, what happens to the balance point?
Solution: Increasing the known voltage will cause the balance point to move towards the positive terminal, as a higher voltage requires a longer length of wire to balance.
Steps: 5
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.
