About the Voltage Divider Calculator
A voltage divider is a simple circuit that divides an input voltage (Vin) into a smaller output voltage (Vout) using two resistors (R1 and R2). This tool calculates the output voltage based on the input voltage and resistor values.
Formula:
The output voltage (Vout) is calculated using the formula: \[ V_{\text{out}} = V_{\text{in}} \times \frac{R2}{R1 + R2} \]
How to Use:
- Enter the input voltage (Vin) in volts.
- Enter the values of R1 and R2 in ohms (Ω).
- Click “Calculate” to get the output voltage (Vout).
Example:
If Vin = 12V, R1 = 1000Ω, and R2 = 2000Ω: \[ V_{\text{out}} = 12 \times \frac{2000}{1000 + 2000} = 8 \, \text{V} \]
