Output Voltage

2.500 V

Resistance Below Wiper5,000 Ω
Resistance Above Wiper5,000 Ω

Output Voltage vs Input Voltage

Potentiometer as Voltage Divider

V_out = V_in x (position / 100)

The wiper divides the pot into two resistors forming a divider. Assumes no load.

Example Calculation

10k pot at 50% on 5 V.

  1. 01V_out = 5 x 0.50 = 2.5 V
  2. 02R_bottom = 5000 ohms, R_top = 5000 ohms
