Q
Q: A potentiometer wire has a length of 10 m and a potential difference of 5 V across it. What is the potential gradient?
Solution:
The potential gradient is calculated as the potential difference divided by the length of the wire: 5 V / 10 m = 0.5 V/m.
Steps: 5
Show Steps
Step 1: Identify the total length of the potentiometer wire, which is 10 meters.
Step 2: Identify the potential difference across the wire, which is 5 volts.
Step 3: Use the formula for potential gradient, which is: Potential Gradient = Potential Difference / Length.
Step 4: Substitute the values into the formula: Potential Gradient = 5 V / 10 m.
Step 5: Calculate the result: 5 V divided by 10 m equals 0.5 V/m.
