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. β—† THE SIMULATOR β—† The heart of E-Light β–Έ A real MNA physics engine solves the entire circuit on every change β€” series, parallel, and three-phase. β–Έ 125+ real industrial components: contactors, MCBs, RCDs, overload relays, VFDs, timers, 3-phase motors, sensors, CTs, energy meters, and more. β–Έ Make it fail safely: overload a breaker, and it trips; drop a phase, and the relay reacts β€” zero risk, zero smoke. β–Έ Live readouts for voltage, current, power, and energy, like a real test bench. β–Έ Practice motor-control wiring: start/stop, delay timers, and seal-in circuits. β—† PROFESSIONAL ENGINEER-GRADE CALCULATORS β—† When you need a fast, defensible answer, 20 are built in: β€’ Ohm's Law β€’ Power (1Ξ¦ / 3Ξ¦) β€’ Voltage Drop β€’ Wire Size β€’ Motor FLC β€’ Breaker Sizing β€’ Short Circuit β€’ Ground Fault Loop β€’ Relay IDMT β€’ Power Factor Correction β€’ VFD Speed β€’ Earthing Conductor β€’ Busbar Sizing β€’ UPS Sizing β€’ Battery Backup β€’ Generator Sizing β€’ Generator Fuel β€’ Residential Load β€’ 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. β—† BUILT FOR LEARNING β—† 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. β—† FREE & PRO β—† 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 β€” start a circuit on one device and continue on another. β—† GROWING WITH EVERY UPDATE β—† New simulator components, calculators, languages, and features continue to be added. β—† WORKS ACROSS YOUR DEVICES β—† Sign in once, and your projects sync across Mobile > Desktop > Tablet. Start a circuit on one device and continue on another. β—† E-LIGHT PRO β—† (auto-renewing subscription) Unlock the complete simulator component library, cloud sync, an ad-free experience, and calculator formulas. β€’ Available as Monthly, Quarterly, or Annual plans β€’ Prices are shown in the app and may vary by region β€’ Payment is charged to your Apple ID upon confirmation of purchase β€’ Renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period β€’ Your account will be charged for renewal within 24 hours prior to the end of the current period β€’ Manage or cancel anytime in your App Store account settings Terms of Use (EULA): https://elight.app/terms Privacy Policy: https://elight.app/privacy
