Question: What happens to the potential difference across a segment of a potentiometer wire if the resistance of the wire is increased?

Options:

Correct Answer: It remains the same.

Solution:

Increasing the resistance of the wire decreases the current, which in turn decreases the potential difference across any segment of the wire.

What happens to the potential difference across a segment of a potentiometer wire if the resistance of the wire is increased?

Step 1: Understand that a potentiometer wire is used to measure potential difference (voltage).
Step 2: Know that the potential difference across a wire depends on the current flowing through it and its resistance.
Step 3: Remember Ohm's Law, which states that Voltage (V) = Current (I) x Resistance (R).
Step 4: If the resistance of the wire is increased, the current flowing through the wire will decrease (assuming the voltage supply remains constant).
Step 5: Since the current decreases and the resistance increases, the potential difference across any segment of the wire will also decrease.
