What happens to the null point in a potentiometer if the resistance of the wire

What happens to the null point in a potentiometer if the resistance of the wire is increased?

What happens to the null point in a potentiometer if the resistance of the wire is increased?

Step 1: Understand what a potentiometer is. It is a device used to measure voltage by balancing it against a known voltage.
Step 2: Know that the null point is the point where the voltage across the wire equals the voltage from the battery.
Step 3: Recognize that the resistance of the wire affects the current flowing through it.
Step 4: When the resistance of the wire is increased, the current flowing through the wire decreases.
Step 5: A decrease in current means that less voltage is dropped across the wire.
Step 6: Since the voltage drop across the wire is less, the null point (where the voltages balance) will move away from the battery.
