Question: What happens to the balancing length if the emf of the cell is increased while keeping the potentiometer wire constant?

Options:

Correct Answer: Balancing length increases

Solution:

Increasing the emf of the cell increases the balancing length, as it requires a longer length to balance the higher voltage.

What happens to the balancing length if the emf of the cell is increased while keeping the potentiometer wire constant?

What happens to the balancing length if the emf of the cell is increased while keeping the potentiometer wire constant?

Step 1: Understand what emf (electromotive force) means. It is the voltage provided by a cell or battery.
Step 2: Know that a potentiometer is a device used to measure voltage by comparing it to a known voltage.
Step 3: Realize that the balancing length is the length of the wire needed to balance the voltage of the cell being measured.
Step 4: When the emf of the cell increases, it means the voltage is higher.
Step 5: A higher voltage requires a longer length of wire to achieve balance with the potentiometer.
Step 6: Therefore, if the emf of the cell is increased while keeping the potentiometer wire constant, the balancing length will also increase.
