About

The Electrical Engineering Calculator is a comprehensive, offline-capable utility designed for professionals, students, and hobbyists in the field of electronics and electrical engineering.

This extension places a powerful suite of engineering tools directly in your browser toolbar, allowing you to perform complex sizing and design calculations without leaving your current tab or requiring an internet connection.

⚡ KEY FEATURES

1. Electrical Power Systems
   **Motor Sizing:** Calculate Full Load Current, Start Current, and Torque for Single and 3-Phase motors. Supports DOL, Star-Delta, Soft Starter, and VFD methods.
   **3-Phase Power:** Compute Real (kW), Reactive (kVAR), and Apparent (kVA) power, alongside Phase Voltage/Current.
  **Transformer Sizing:** Determine required kVA ratings for various load types (Resistive, Motor, Nonlinear).
   **Power Factor Correction:** Calculate the required Capacitor Bank (kVAR) to improve system efficiency.
   **Star-Delta:** Conversion tool for resistive networks.

*2. Electronics Design**
   **Resistor Color Codes:** Interactive 4-Band and 5-Band decoder.
   **PCB Trace Calculator:** Calculate required trace width based on current and temperature rise (IPC-2221 standard).
   **Ohm's Law:** Instant calculation of Voltage, Current, Resistance, and Power.
   **Voltage Divider:** Design divider circuits with standard E-series resistors.
   **555 Timer:** Astable and Monostable circuit design (Frequency, Duty Cycle, Pulse Width).
   **Op-Amp:** Configurations for Non-Inverting, Inverting, Differential, and Comparators.
   **Filters:** Active/Passive filter design (Low-pass, High-pass, Band-pass).
   **Battery Life:** Estimate runtime based on battery capacity and load current.

*3. Solar Energy Systems**
   **Panel Sizing:** Calculate array size based on daily energy consumption and local irradiation.
   **Inverter Sizing:** Match inverter capacity to your solar array (including Over/Under-sizing ratios).
   **Battery Bank:** Size your energy storage for specific days of autonomy.

*4. Converters**
   **Unit Converter:** Engineering prefixes (pico to Tera), Area, Volume, and Temperature.
   **Number Systems:** Real-time conversion between Binary, Octal, Decimal, and Hexadecimal.
   **SI ↔ Imperial:** Instant conversion for field measurements (Length, Weight, Volume, Area).

*🔒 PRIVACY & OFFLINE USE**
   **100% Offline:** This extension does not require an internet connection to function.
   **Local Calculation:** All math is performed locally in your browser.
  **No Tracking:** We do not collect, store, or transmit any user data.
