In a potentiometer experiment, if the balance point is found at 4 m with a 12 V battery, what is the voltage across a 2 m length of the same wire?

In a potentiometer experiment, if the balance point is found at 4 m with a 12 V battery, what is the voltage across a 2 m length of the same wire?

Step 1: Understand that a potentiometer measures voltage using a wire with a uniform potential gradient.
Step 2: Identify the total voltage provided by the battery, which is 12 V.
Step 3: Note the length of the wire where the balance point is found, which is 4 m.
Step 4: Calculate the potential gradient (voltage per meter) by dividing the total voltage by the length of the wire: 12 V / 4 m = 3 V/m.
Step 5: Determine the length of the wire for which you want to find the voltage, which is 2 m.
Step 6: Calculate the voltage across the 2 m length using the potential gradient: 3 V/m * 2 m = 6 V.
