Offline electrical engineering suite. Solar, Motors, Resistors, and more. 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. **Version:** 1.0.0 **Developer:** TechnoSkill
