ElectricWorks

Electric Works is a schematic editor with a circuit simulator built in. Place parts, draw wires, and the circuit runs while you build it. Every wire shows its voltage and every part its current. Lamps glow, motors spin, and fuses and breakers trip when they should.

It's made for anyone who works with electricity: students learning Ohm's law, hobbyists wiring a car, camper or workshop, electricians planning a circuit, and engineers who want a quick answer they can trust.

• 67 parts in 9 categories: resistors, capacitors, transistors and op-amps; switches, relays, contactors and timers; breakers, fuses, overloads and GFCIs; lamps, LEDs, heaters, motors, pumps and transformers; car batteries, alternators, starters and solar panels.

• ANSI or IEC symbols, multiple sheets, net labels, notes, copy and paste.

• Type values the way you write them: 4.7k, 4,7k or 4k7.

• 16 ready-made examples, from a voltage divider to a car's starting and charging system and a 3-phase motor starter.

Parts behave like the real thing:

• Breakers, fuses, overloads and GFCIs trip on their real time-current curves.

• Light bulbs draw an inrush current when they're switched on cold.

• Motors have back-EMF, slip, starting current and stall.

• Transformers sag under load, and relay coils kick back when they're switched off.

• Batteries charge and discharge, with the time to full and the time to empty.

• Diodes, transistors and op-amps use datasheet models.

Simulate DC, AC steady state, transients (watch a motor start or a capacitor charge, millisecond by millisecond) and AC frequency sweeps. The results are cross-checked against ngspice, the reference open-source SPICE simulator, on every built-in example.

Press F3 and your circuit becomes a 3D scene: parts at their true relative size, cables coloured by voltage, and glowing beads that show the current flowing. Lamps light, motors spin, switches flip and breakers trip, live.

• Real wires: give any wire a size (AWG or mm²), copper or aluminium, and a length. The simulation then includes its resistance, voltage drop and heat.

• Electrical rule check: short circuits, wire ratings (NEC 310.16 and IEC 60364-5-52), voltage drop, interrupting ratings and part ratings.

• Fault-current study: the prospective short-circuit current at every point, checked against each breaker's interrupting rating.

• Schedules: load (panel) and wire schedules, and a bill of materials, exported as CSV.

• PDF export on A4 or US Letter, with a title block and report pages.

• SPICE export: a netlist that reproduces ElectricWorks' results in any SPICE program.

• Beginner mode explains every part in plain words, updated live: why a lamp is dim, where the voltage went, how hard a wire is working.

• Mistakes show up on the drawing: short circuits, overloaded wires and blown fuses are marked in red.

• Calculators for Ohm's law, resistor colour codes, series and parallel, LED resistors and wire size.

• Professional mode brings the numbers and the pro tools to the front when you're ready.

• One small program (about 17 MB) for 64-bit Windows 10 and 11.

• Works offline: no account, no subscription, nothing sent anywhere.

• Your circuits are files you save wherever you like.

ElectricWorks is a design and learning tool. Always follow your local electrical code, and have mains wiring done or checked by a qualified electrician.
