RC Circuit vs Voltage Divider Calculator

This app is used to calculate the RC charging and RC filter circuit. It is suitable for hobbyist or electronic engineer. Features * Calculate time constant from R, C * Find component value R,C from time constant * Get voltage at time t in RC charging / discharging * Calculate cutoff frequency by R, C * Find component value R,C from cutoff frequency * Save data to CSV files * Upload CSV via AirDrop / iCloud Drive * Support English, Traditional Chinese, Simplified Chinese, German, French, Italian, Spanish, Portuguese, Japanese

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.
