A 10 kΩ potentiometer has 24 V across its outer terminals. The wiper is at the exact centre of its travel. What voltage is between the wiper and one outer terminal?

  1. 0 V
  2. 24 V
  3. 6 V
  4. 12 V
Show answer

Correct answer: 12 V

At the centre position the wiper takes half of the applied voltage, whatever the end-to-end resistance is.
