## Description

Looks simple, solves like an engineer. Build a real panel, hit Run, and a real physics engine takes over — breakers trip, motors spin. Plus 20 engineer-grade calculators.

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 into a single 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, delay timers, and seal-in circuits.

◆  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.

◆  FREE & PRO  ◆

The simulator and all 20 calculators are free to use, with 10 components to try the canvas, local project saves, and occasional ads. E-Light Pro removes ads, reveals the formula behind every calculator, and unlocks the full 125+ component library plus cloud sync — start a circuit on one device and continue on another.

◆  GROWING WITH EVERY UPDATE  ◆

New simulator components, calculators, languages, and features continue to be added.

◆  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  ◆
