Design faster, check formulas instantly, and get confident answers—whether you’re wiring a prototype, laying out a PCB, or verifying lab results. This all-in-one toolkit brings together the most-used electronics calculators so you don’t have to jump between apps or spreadsheets. Core Circuits & Passives • Ohm’s Law (V, I, R, P) • Resistor color code (through-hole & SMD) • Series/parallel & voltage divider • Capacitance & capacitor impedance (RC) • Inductance/reactance/admittance; coil/loop inductance • Battery life estimation • RMS/peak/peak-to-peak voltage • Decibel (dB) converters for power/voltage levels Analog & RF Essentials • Op-amp gain/voltage and inverting resistor calculators • Impedance matching: π-match and T-match • RF power: ratio/units conversion, PAE, N-way power divider • dB/dBm helpers for quick link-budget math These are the same families of tools engineers rely on for day-to-day analog and RF work. PCB & Signal Integrity (EDA) • Microstrip/stripline impedance (single-ended & differential) • Trace width and max current • Crosstalk (edge/broadside), wire/microstrip inductance These capabilities mirror what dedicated PCB toolkits and online impedance calculators provide—now in one place on your phone. Electromechanical & Power • Lenz’s & Faraday’s laws (induced EMF) • Torque conversion and stepper motor helpers • Flyback SMPS building blocks • Heat sink basics & power density • Peak/peak-to-peak/RMS and power conversions These bridge the gap between bench calculations and real hardware choices. Physics & Foundations • Lorentz force, electrical energy, RC time constant, LC tank resonance—handy checks for labs and exams alike. Why this app? • Comprehensive: from Ohm’s Law and resistor codes to PCB impedance and RF power—covering the everyday set engineers actually use. • Built for speed: clean inputs, clear results, and units you expect. • For everyone: students learning the basics, makers iterating quickly, and professionals verifying designs. Perfect for: electronics labs, field service, ham/RF projects, PCB layout checks, audio/dB work, and rapid “sanity-check” calculations during reviews.
