E-Light: Circuit Simulator
E-Light looks simple. It solves like an engineer. Learn electrical engineering by building real circuits. E-Light combines an interactive circuit simulator with professional electrical calculators in one modern learning platform. At the heart of E-Light is a circuit simulator powered by a real Modified Nodal Analysis (MNA) physics engine. Place industrial electrical components onto the canvas, connect them terminal-to-terminal, press *Run*, and watch your circuit come alive with live voltage, current, and power calculations. ``` ◆ THE SIMULATOR ◆ The heart of E-Light ``` ▸ A real MNA physics engine solves the entire circuit on every change — series, parallel and three-phase ▸ 125+ real industrial components: contactors, MCBs, RCDs, overload relays, VFDs, timers, 3-phase motors, sensors, CTs, energy meters and more ▸ Make it fail safely: overload a breaker, and it trips; drop a phase, and the relay reacts — zero risk, zero smoke ▸ Live readouts for voltage, current, power, and energy, like a real test bench ▸ Practice motor-control wiring: Start/Stop, On-Time Delay, reversing, and seal-in circuits ``` ◆ PLUS PROFESSIONAL ENGINEER-GRADE CALCULATORS ◆ ``` When you need a fast, defensible answer, *20 are built in*: ◈ Ohm's Law ◈ Power (1Φ / 3Φ) ◈ Voltage Drop ◈ Wire Size ◈ Motor FLC ◈ Breaker Sizing ◈ Short Circuit ◈ Ground Fault Loop ◈ Relay IDMT ◈ Power Factor Correction ◈ VFD Speed ◈ Earthing Conductor ◈ Busbar Sizing ◈ UPS Sizing ◈ Battery Backup ◈ Generator Sizing ◈ Generator Fuel ◈ Residential Load ◈ Lighting Design — built to recognized standards. With *Pro*, each calculator also reveals the equation behind the result, so you can check the formula, not just the number. ``` ◆ BUILT FOR LEARNING ◆ ``` Designed for engineers, technicians, educators, and students who want to learn, and instructors who want a safe, zero-equipment lab in the classroom. Practice and better understand electrical systems in a safe digital environment. ``` ◆ A MODERN ELECTRICAL LAB ◆ ``` ✦ No physical equipment required ✦ Safe experimentation with no live voltage ✦ Learn anywhere, on phone or tablet ✦ Designed to support practical electrical education ``` ◆ WORKS ACROSS YOUR DEVICES ◆ ``` Sign in once, and your projects sync across *Mobile ▸ Desktop ▸ Tablet*. Start a circuit on one device and continue on another. ``` ◆ E-LIGHT PRO ◆ ``` E-Light Pro is an optional subscription that removes ads, reveals the formula behind every calculator, and unlocks the full 125+ component library and cloud sync. The simulator and all 20 calculators are available without a subscription, with a starter set of components and local saves.
