Electronics Toolkit - An Electronics Lab in Your Pocket

A comprehensive electronics toolkit for engineers, students, electricians, and electronics enthusiasts. All the essential tools you need to design, analyze, and repair electronic circuits.

🔧 9 PROFESSIONAL TOOLS

📊 Ohm's Law: Quickly calculate voltage, current, resistance, and power. Simply input any two values ​​to calculate the remaining two.

🎨 Resistor Color Coder: Decode 4, 5, and 6-band resistor color codes. Determine resistance values, tolerances, and temperature coefficients accurately.

💡 LED Resistance Calculator: Calculate the appropriate resistance for an LED circuit. Input the supply voltage, forward voltage, and LED current to get accurate results.

🔄 Unit Conversion: Quickly convert between voltage units (V, mV, kV), current units (A, mA, µA), resistance units (Ω, kΩ, MΩ), and power units (W, mW, kW).

⚡ Voltage Divider: Calculates the output voltage of a two-resistor voltage divider circuit. Displays the voltage divider ratio and detailed results.

🔋 Capacitor Code: Decodes the 3-digit code on ceramic capacitors. Automatically converts to picofarads (pF), nanofarads (nF), and microfarads (µF).

🔗 Series/Parallel: Calculates the total resistance of resistors connected in series and parallel. Add an unlimited number of resistors and see the results instantly.

🎨 Reverse Color Code: Enter the resistance value to see the corresponding color band. Supports 4-band and 5-band display.

📖 Electronics Toolkit: Quickly look up important formulas: Ohm's law, power, voltage divider, capacitor, frequency, and impedance.

👥 WHO IS IT FOR?

• Electronics and electrical engineers
• Electrical and electronics engineering students
