How to Use This Calculator

This voltage divider calculator helps you determine the output voltage (Vout) of a basic two-resistor voltage divider circuit.

Instructions:

1. Enter your input voltage (Vin) in volts
2. Enter the values for R1 and R2 in ohms (Ω)
3. The calculator will automatically compute:
   • Output voltage (Vout)
   • Current through the circuit
   • Power dissipated by each resistor
4. Use the preset dropdowns to quickly select common resistor values
5. Export your results as PDF or CSV if needed

Voltage Divider Formula:

Vout = Vin × (R2 / (R1 + R2))

Applications:

• Sensor interfacing
• Signal conditioning
• Reference voltage creation
• Biasing transistor circuits
