A linear potentiometer has 24 V across its track. The wiper is one quarter of the way up from the bottom terminal. What is the voltage from the wiper to the bottom terminal?

  1. 6 V
  2. 18 V
  3. 12 V
  4. 24 V
Show answer

Correct answer: 6 V

The output is set by the wiper position as a fraction of the track: 1/4 × 24 V = 6 V.
