Q
Q: If a potentiometer wire has a potential difference of 12 V and a length of 6 m, what is the potential gradient?
Solution:
The potential gradient is calculated as the potential difference divided by the length of the wire: 12 V / 6 m = 2 V/m.
Steps: 6
Show Steps
Step 1: Identify the potential difference given in the problem, which is 12 V.
Step 2: Identify the length of the potentiometer wire, which is 6 m.
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 = 12 V / 6 m.
Step 5: Perform the division: 12 V divided by 6 m equals 2 V/m.
Step 6: Conclude that the potential gradient is 2 V/m.
