Q
Q: If the known voltage in a potentiometer is 12 V and the length of the wire is 6 m, what is the potential gradient?
Solution:
The potential gradient is calculated as V/L = 12 V / 6 m = 2 V/m.
Steps: 6
Show Steps
Step 1: Identify the known voltage, which is 12 V.
Step 2: Identify the length of the wire, which is 6 m.
Step 3: Use the formula for potential gradient, which is V/L (voltage divided by length).
Step 4: Substitute the known values into the formula: 12 V / 6 m.
Step 5: Perform the division: 12 divided by 6 equals 2.
Step 6: State the result: The potential gradient is 2 V/m.
