Voltage Divider ની ગણતરી કેવી રીતે કરવી
Voltage Divider શું છે?
Calculates output voltage from a resistor network dividing input voltage. Used for ADC inputs, sensor interfaces, and voltage scaling.
સૂત્ર
Formula: Vout = Vin × (R2 ÷ (R1 + R2))
- R2
- R2 value — Variable used in the calculation
- R1
- R1 value — Variable used in the calculation

Common Mistakes to Avoid
- ✕Not buffering voltage divider with low-impedance load
- ✕Using very small resistor values (excessive power)
Frequently Asked Questions
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.
