learn.whatIsHeading
Calculates output voltage from a resistor network dividing input voltage. Used for ADC inputs, sensor interfaces, and voltage scaling.
सूत्र
Formula: Vout = Vin × (R2 ÷ (R1 + R2))
- R2
- R2 value — Variable used in the calculation

सामान्य गलतियां जिनसे बचना है
- ✕Not buffering voltage divider with low-impedance load
- ✕Using very small resistor values (excessive power)
अक्सर पूछे जाने वाले प्रश्न
What affects voltage divider accuracy?
Load impedance (must be much higher than resistor values), temperature stability, resistor tolerance.
How do I buffer a voltage divider?
Use op-amp buffer to isolate divider from load; prevents voltage drop under load.
