Electrical Engineering Toolkit 4+

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.
