FormulaSimLab

Electronics Formula Calculator

R19.99

Instant electronics calculator: Ohm’s law, power, voltage divider, resistors, RC, op-amp gains & LED resistor. Works offline, no accounts, no data collected. FormulaSimLab is a clean, fast, and fully offline electronics calculation app designed for students, hobbyists, technicians, and engineers who want clarity instead of clutter. Instead of forcing you into fixed calculations, FormulaSimLab always starts by asking a simple question: “Which parameter do you want to calculate?” You choose the unknown value, enter the known ones, and the app instantly solves it for you. All Essential Electronics Formulas in One App In daily practice, these formulas are usually scattered across different calculators, websites, or books. FormulaSimLab brings them together in one unified calculator, with a consistent interface and clear circuit diagrams for every formula. Included Formulas & Calculations FormulaSimLab currently includes 10 essential electronics formulas, each with full parameter selection: 1)Ohm’s Law Calculate V, I, or R with a visual circuit diagram and clear unit labels. 2)Electric Power Calculate P, V, or I using the power formula, ideal for quick energy and load checks. 3)Voltage Divider Calculate Vin, Vout, R1, or R2 with a complete divider schematic clearly shown on screen. 4)Series Resistors Choose the number of resistors, enter individual values, and instantly calculate total resistance (Req). 5)Parallel Resistors Calculate equivalent resistance for multiple parallel resistors using the correct reciprocal formula. 6)RC Time Constant Calculate the time constant (τ) using resistance and capacitance values, perfect for timing and filter basics. 7)Capacitive Reactance Calculate Xc using frequency and capacitance, commonly needed in AC circuit analysis. 8)Op-Amp Non-Inverting Amplifier Calculate Av, Rf, or Rg, with a clear non-inverting op-amp circuit diagram. 9)Op-Amp Inverting Amplifier Calculate Av, Rf, or Rin, including the correct negative gain relationship and schematic. 10)LED Series Resistor Calculate R, Vs, Vled, or Iled, making it easy to safely design LED circuits. Designed for Learning and Real Use Every calculation screen includes: -A clear formula display -Unit-aware input fields -Instant result updates -A visual circuit diagram that matches the calculation This makes FormulaSimLab useful not only as a calculator, but also as a learning and reference tool. Simple, Fast, and Offline No accounts No data collection No internet required No ads No distractions Just open the app, choose a formula, select what you want to calculate, and get the result instantly. Who Is FormulaSimLab For? -Electronics students -Makers & hobbyists -Technicians -Engineers -Anyone who wants quick, reliable electronics calculations in one place FormulaSimLab replaces multiple calculators with one consistent, visual, and easy-to-use electronics toolkit—always in your pocket. FormulaSimLab is built with a strong focus on usability and clarity. Every screen follows the same logic, so once you learn one formula, you can use all others without confusion. Input fields are clean, readable, and labeled with correct electrical units, reducing mistakes during calculations. The app is especially useful in real-life scenarios such as breadboard prototyping, exam preparation, lab work, field measurements, and quick design checks. Instead of memorizing multiple equations or searching online, you can verify values instantly with confidence. FormulaSimLab does not store, track, or share any user data. All calculations are performed locally on your device, making the app reliable even without an internet connection. This also ensures fast response times and a distraction-free experience. Whether you are learning electronics for the first time or need a dependable calculator in your daily workflow, FormulaSimLab provides a practical, visual, and efficient solution—combining essential electronics knowledge into a single, well-organized app.
