Electrical Engineering Toolkit

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.
