In a potentiometer setup, if the balancing length is found to be 50 cm for a 12V battery, what is the potential difference per cm?
Correct Answer: 0.24 V/cm
- Step 1: Identify the total voltage from the battery, which is 12V.
- Step 2: Identify the balancing length measured on the potentiometer, which is 50 cm.
- Step 3: To find the potential difference per cm, divide the total voltage by the balancing length.
- Step 4: Perform the calculation: 12V divided by 50 cm equals 0.24 V/cm.
- Step 5: Conclude that the potential difference per cm is 0.24 V/cm.
