Q: A potentiometer wire has a uniform cross-section and a potential difference of 12V across it. If the length of the wire is 6m, what is the potential gradient?

Solution: Potential gradient = Voltage / Length = 12V / 6m = 2 V/m.

Steps: 5

Step 1: Identify the total voltage across the potentiometer wire, which is given as 12V.
Step 2: Identify the length of the wire, which is given as 6m.
Step 3: Use the formula for potential gradient, which is Potential Gradient = Voltage / Length.
Step 4: Substitute the values into the formula: Potential Gradient = 12V / 6m.
Step 5: Calculate the result: 12V divided by 6m equals 2 V/m.
