Output Voltage vs Input Voltage
Fórmula
## 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.
Ejemplo Resuelto
10k pot at 50% on 5 V.
- 01V_out = 5 x 0.50 = 2.5 V
- 02R_bottom = 5000 ohms, R_top = 5000 ohms
Preguntas Frecuentes
Does load affect output?
Yes. A low-impedance load reduces V_out. Use a buffer for sensitive circuits.
Linear vs logarithmic?
Linear changes uniformly. Log taper matches human hearing perception.
How to choose pot value?
Pick 10x higher than load impedance. Common: 1k, 10k, 100k.
