โน๏ธ About Voltage Divider Calculator
A Voltage Divider is a fundamental linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin). It is commonly used to create reference voltages, reduce signal levels (level shifting), or measure high voltages with a microcontroller's ADC.
The standard formula is:
Vout = Vin ร (R2 / (R1 + R2))
This tool allows you to:
- Calculate Vout: Enter Vin, R1, and R2.
- Calculate R1 or R2: Enter the desired Vout and one resistor value to find the other.
๐ How to use Voltage Divider Calculator
- 1. Enter the Input Voltage (Vin).
- 2. Enter values for two of the remaining three fields (R1, R2, or desired Vout).
- 3. The tool will calculate the missing value and show the current draw and power dissipation.
โ Frequently Asked Questions
Can I use a voltage divider to power a motor?
No. Voltage dividers are only for low-current signals. Drawing significant current from the output (Vout) will cause the voltage to drop significantly due to loading effects.
