Solve Vin, Vout, R1, R2, Load
Free · Designed for iPad. Not verified for macOS.
Voltage Divider Calculator
Easily solve voltage divider circuits
Enter any 3 known values —
• Input Voltage (Vin)
• Output Voltage (Vout)
• Resistor 1 (R1)
• Resistor 2 (R2)
and the app instantly calculates the fourth.
NEW in this version:
• Loaded divider support — add an optional Load Resistance (RL) to see the real output voltage under load
• Power dissipation — see P(R1) and P(R2) instantly, so you can pick the right resistor wattage
• Standard values — get the nearest E24 resistor value for your calculated resistance
• Completely ad-free — no banners, no pop-ups, no tracking
Supports Ohms and Kilo-Ohms, with instant results as you type.
Perfect for students, hobbyists, and engineers doing quick, accurate circuit analysis and design.
Compatible with both iPhone and iPad.
