VoltDivide

VoltDivide is a voltage divider calculator.

Features:
Forward calculation: Enter Vin, R1, and R2 to get Vout, current, power, and ratio
Reverse calculation: Enter target Vout and R1 to find the required R2 value
E12 series resistor quick selector with decade multiplier support
Apply selected E12 values directly to the divider calculator
Circuit reference guide with formulas, design tips, and common applications
Nearest E12 matching with deviation analysis
No internet required for calculations
No data collection - your values stay on your device
Formula: Vout = Vin × R2 / (R1 + R2)
