Electrical Wiring Simulator vs σT

Electrical Wiring Simulator is a hands-on circuit simulator for electrician training, apprentices, and TVET students. Practice DC and AC wiring, relays, motors, and Arduino circuits on your phone—safe, step-by-step, anytime, anywhere. Join 1M+ learners building real-world wiring skills without tools, live voltage, or a physical lab. MASTER ELECTRICAL WIRING – NO TOOLS NEEDED Learn and simulate house wiring, control circuits, and industrial diagrams right from your device. Designed for students, apprentices, electricians-in-training, instructors, and hobbyists who want hands-on learning—without the risk. WHAT YOU'LL LEARN • Load control and switching techniques • Series and parallel DC and AC circuits • Relay, contactor, and motor control wiring • Basic electronics exercises • Electrical diagrams and component layout • Load balancing and voltage checks • Real-time troubleshooting and simulation EXAM & CERTIFICATION PREP Build skills for journeyman electrician practice, NEC-style wiring scenarios, and technical assessments. Whether you are preparing for a trade exam, skills test, or classroom lab, EWS helps you practice diagrams, switching, and fault-finding before the real board. EWS is a training simulator—it does not grant professional certification. Always follow local electrical codes, instructor guidance, and safety procedures. WHY LEARNERS CHOOSE EWS • Safe, hands-on circuit simulation • Step-by-step guided practice and tutorials • Built for technical and vocational training • Used in TVETs and training centers worldwide • Mobile-first design for practice on the go • Save progress and track your learning path GO PRO FOR THE FULL SANDBOX • Unlock all circuit modules and exercise tracks • Ad-free learning environment • Unlimited local saves • LMS integration for schools and training programs • Certificate of Completion • Pro-only features, components, and control boards CURRICULUM TRACKS INCLUDE • Basic electricity and DC circuits • AC series and parallel wiring • Relays and solenoids • Contactors and motors • Electronics • EIM and assessment modules Whether you are an apprentice starting out, a student in a technical program, or a professional brushing up on wiring diagrams and control logic, Electrical Wiring Simulator helps you build skills that matter—in the classroom, on the job, and before exam day. PRO OPTIONS • Pro Yearly — 1-year auto-renewable subscription with free trial where offered • Pro Lifetime — one-time purchase • Pro unlocks the full curriculum, unlimited local saves, and Pro-only features and components SUBSCRIPTION TERMS • Price is shown in your local currency before purchase • Payment is charged to your Apple ID at confirmation of purchase • Yearly Pro renews automatically unless canceled at least 24 hours before the end of the current period • Your account is charged for renewal within 24 hours before the end of the current period • Manage or cancel anytime in Apple ID Account Settings Electrical Wiring Simulator is a learning aid for electrical wiring training. It does not replace certified instruction, licensing, or compliance with local electrical codes. Never perform real electrical work without proper authorization, supervision, and safety procedures.

σT is a precision tool for physics students and researchers who need to propagate measurement uncertainties through calculations. Enter your experimental data, and σT handles the error math automatically. **FIVE ERROR MODES** Configure uncertainties in your data to match your orignal measurement method: • Constant — for physical constants and exact values • Absolute — fixed ±error (ruler measurements, digital readouts) • Relative — percentage-based uncertainty • Combined — both absolute and relative components (many typical multimeters) • Per-Value — individual error for each measurement **AUTOMATIC PROPAGATION** Create derived values and watch uncertainties flow through the calculation chain. σT uses Gaussian error-propagation and pre-calculated derivative-based methods to compute propagated errors correctly when combining independently measured variables. Available operations: • Basic: add, subtract, multiply, divide, reciprocal • Functions: exp, ln, sin, cos, normalize • Statistical & Sample Statistics: mean with standard error, average step width • Advanced: weighted sums, weighted products, polynomials • Physics: Lorentz factor (relativistic gamma), Logit sigmoid (Fermi-Dirac statistics) **INTERACTIVE CHARTS** Visualize your data with proper error bars. Pinch to zoom, drag to pan, double-tap to auto-fit. Add mathematical function overlays to compare your measurements against theoretical predictions, identify eligible parameter ranges matching your measurements. **EXPORT YOUR WORK** • CSV and TSV export for spreadsheets and analysis tools • High-resolution PNG charts for lab reports • Complete project files for sharing with classmates or colleagues • Copy data to clipboard with a swipe and continue in Sheets or Excel with errors in place **DESIGNED FOR LAB WORK** σT adapts to your device: • iPhone: Full-featured portable lab companion • iPad: Side-by-side layout for efficient data entry • Mac: Native desktop experience via Catalyst **YOUR DATA, YOUR DEVICE** All measurements are stored locally. No account required, no cloud sync, no tracking. σT works completely offline.
