About ElectraSim

ElectraSim is a comprehensive, browser-based electrical circuit and wiring simulator designed for students, teachers, electricians, and hobbyists. It provides a risk-free environment to build, simulate, and troubleshoot house-wiring circuits without the need for downloads, accounts, or server connections.

Key Features

  • Real-Time Simulation: Watch electricity flow with animated wires, spinning fans, and lighting bulbs at 60fps.
  • Drag & Drop Components: Access over 16 component types, including MCBs, RCDs, RCBOs, switches, sockets, and motors.
  • Fault Detection: Practice identifying and diagnosing open circuits, short circuits, reverse-polarity, and missing-earth faults.
  • Smart Tools: Features auto-routing for wires, multi-select alignment, and a grid-snapping system for professional diagrams.
  • Import & Export: Save work locally as JSON, export diagrams as PNG or SVG, or generate shareable URLs.

How it works

  1. Launch: Open the simulator directly in your browser; it works offline after the first visit.
  2. Build: Drag components from the palette onto the canvas.
  3. Wire: Connect components using the auto-routing tool.
  4. Simulate: Press Run to toggle switches, trigger faults, and observe circuit behavior in real-time.
