In a potentiometer experiment, if the known voltage is increased, what happens to the balance length?
It increases
It decreases
It remains the same
It becomes zero
If the known voltage is increased, the balance length will also increase, as a higher voltage will require a longer length of wire to achieve balance.

Q
Q: In a potentiometer experiment, if the known voltage is increased, what happens to the balance length?
Solution: If the known voltage is increased, the balance length will also increase, as a higher voltage will require a longer length of wire to achieve balance.
Steps: 5
Step 1: Understand that a potentiometer is used to measure voltage by balancing it against a known voltage.
Step 2: Recognize that the balance length is the length of wire needed to achieve this balance.
Step 3: Know that if the known voltage increases, more voltage is needed to balance it.
Step 4: Realize that a longer length of wire is required to achieve this balance with the higher voltage.
Step 5: Conclude that as the known voltage increases, the balance length also increases.
