Electrical Engineering Ca

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).
