Q: A potentiometer wire has a uniform cross-section and a length of 10 m. If a potential difference of 5 V is applied, what is the potential gradient?

Solution: The potential gradient is calculated as V/L = 5 V / 10 m = 0.5 V/m.

Steps: 6

Step 1: Identify the total potential difference (V) applied across the potentiometer wire. In this case, V = 5 V.
Step 2: Identify the length (L) of the potentiometer wire. Here, L = 10 m.
Step 3: Use the formula for potential gradient, which is given by the formula: Potential Gradient = V / L.
Step 4: Substitute the values into the formula: Potential Gradient = 5 V / 10 m.
Step 5: Perform the division: 5 V divided by 10 m equals 0.5 V/m.
Step 6: Conclude that the potential gradient is 0.5 V/m.
