What is the effect of increasing the resistance of the potentiometer wire on the potential gradient?

Step 1: Understand what a potentiometer is. It is a device used to measure voltage by comparing it to a known voltage.
Step 2: Know that the potentiometer wire has a certain resistance.
Step 3: Remember that the potential gradient is the change in voltage per unit length of the wire.
Step 4: If we increase the resistance of the potentiometer wire, we are making it harder for current to flow through it.
Step 5: With higher resistance and constant voltage, the current flowing through the wire decreases.
Step 6: Since the potential gradient depends on the current, a decrease in current means a decrease in the potential gradient.
Step 7: Therefore, increasing the resistance of the potentiometer wire decreases the potential gradient.
