Build your circuit with your
finger, wire it up and simulate instantly. Works OFFLINE: once installed it
needs no internet.

▶ THE SIMULATION COMES ALIVE
It is not a static drawing: CURRENT flows through the wires as particles, the
lamp LIGHTS UP with power, the motor SPINS with current and the buzzer SOUNDS while it is powered. You see what happens, not just numbers.

▶ REAL ANALYSIS
• DC: operating point, voltages and currents node by node.
• Transient: built-in oscilloscope with cursors, measurements (Vpp, RMS,
frequency) and adaptive step for precise traces.
• Bode (AC): frequency response, gain and phase.
• DC sweep, and a live results panel component by component.

▶ POWER ELECTRONICS (what other simulators leave out)
• Thyristor (SCR), TRIAC and DIAC with phase control — build the real wall
DIMMER and watch it chop the waveform.
• IGBT for switching and choppers.
• Optocoupler and transformer for isolation.
• Relay with real physics: inductive coil, hysteresis and flyback spike.
The industrial-electronics lab the technical curriculum needs.

▶ 76 COMPONENTS
Resistors, capacitors (including polarized electrolytics), inductors, diodes,
LED, RGB LED, LED bar, Zener, Schottky, bridge rectifier, lamp, heater, fuse,
potentiometer, photoresistor, NTC thermistor, DC motor, relay, buzzer, speaker,
7-segment display, LCD, battery with internal resistance, DC / sine / pulse
(PWM) / triangle / sawtooth / noise / FM sources, BJT and MOSFET transistors,
Darlington pairs, op-amp, voltage regulator, transformer, the NE555 timer, and a
full digital set: 2- and 3-input gates, Schmitt trigger, flip-flops, half and
full adder, decade counter, multiplexer, decoder and monostable. Edit any value
with engineering notation (4.7k, 1µ, 4k7).

▶ 56 GUIDED EXAMPLES
Dividers, rectifiers, Wheatstone bridge, filters and resonance (Bode), a
mains-to-12 V power supply, op-amp amplifiers, 555 oscillator and monostable, a
relay switching a lamp, a DIAC dimmer, a three-phase line, a logic latch, a
light alarm and more — each with its animated schematic and its explanation.

▶ FORMULAS THAT DO THE MATH
24 calculators built into the theory sheets: Ohm's law, series and parallel,
dividers, RC and RL time constants, reactance, cutoff frequency, resonance, the
LED resistor, 555 astable and monostable and more. Leave the unknown blank and it solves it, or load the values from the circuit on screen. It also suggests the nearest real E24/E12 resistor and shows the error.

▶ MADE FOR LEARNING
• 13 languages: English, Spanish, Portuguese, German, French, Italian, Polish, Russian, Turkish, Hindi, Urdu, Japanese and Chinese, each with its flag.
• Touch editor with floating buttons: place a part, wire pin to pin with two
taps, lock the circuit to drag a whole connected block.
• Warnings that teach: it tells you when an electrolytic is backwards or when a part runs far over its limit — an LED with no resistor lights up here and burns out on the bench. And a fuse blows at its rated current: you see the
filament break.
• Settings screen: light or dark theme, text size, values on the grid and a
step-by-step tutorial.
• Save your circuits, export the schematic or the scope trace to PNG and share them from the app.

▶ LIGHT AND FAST
Runs even on school netbooks and Chromebooks. Its own simulation engine, no gimmicks: it solves with the same methods as a professional simulator — the transistors carry their junction capacitance, so oscillators and switching circuits settle as they do on the bench.

Free, with a banner ad at the bottom. A single optional purchase removes the ads forever.

Ideal for analog and power-electronics classes: rectifiers, amplifiers, filters,
phase control with thyristors, timers and digital circuits — experiment without burning anything. ## Rankings - #974,565 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.WAKE_LOCK` - `com.android.vending.BILLING` - `com.circuitos.simulador.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` ## Similar extensions and apps - [Jelc.Builder](https://chrome-stats.com/d/com.circuitos.generador) — 26 users - [Electric Circuit Simulator](https://chrome-stats.com/d/com.thetwins.electricsimulator) — 10,762 users - [Circuit Simulator](https://chrome-stats.com/d/com.izatm.circuitsimulator) — 1,110 users - [ElectroSim: Electrical Wiring](https://chrome-stats.com/d/com.LouieJuera.ElectroSimPro) — 99,167 users, 3.87 / 5 - [Circuit Wiring Simulator](https://chrome-stats.com/d/cc.feisuo.wiringoverseas) — 25,494 users - [CircuitX: Circuit Simulator](https://chrome-stats.com/d/com.abdo.circuitx) — 57,069 users, 4.55 / 5 - [EveryCircuit](https://chrome-stats.com/d/com.everycircuit.free) — 5,495,409 users, 4.26 / 5 - [Electronic Circuits Learning](https://chrome-stats.com/d/com.electroniccircuitsapp) — 91 users - [Electric Circuit Studio](https://chrome-stats.com/d/com.ecstudiosystems.electriccircuitstudio) — 1,561,498 users, 3.78 / 5 - [Circuit Champ](https://chrome-stats.com/d/com.envizzion.circuitchamp) — 32,938 users, 3.40 / 5 - [Circuit Sim · 회로 시뮬레이터](https://chrome-stats.com/d/com.dolab.circuitsim) — 15 users - [Elektroappka](https://chrome-stats.com/d/com.dlectrodev.elektroappka) — 222 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.circuitos.simulador)
