Free Ohm’s Law Lab Simulator
Ohm’s Law Lab Simulator lets students adjust power supply voltage, resistor values, series or parallel wiring, ammeter, voltmeter, and bulb options while current, voltage, resistance, power, data records, and the V-I graph update in real time.
Built for Ohm’s law homework, circuit lab practice, series and parallel circuit review, and unknown resistance measurement.
Start Ohm’s Law Lab Simulator here: set voltage and resistance, choose the connection mode, connect meters or a bulb, record readings, and watch the V-I graph prove the relationship between voltage and current.
Change the power supply, resistor values, connection mode, meters, and bulb before recording each reading.

Experiment conclusion
Ohm’s Law Lab Simulator uses ideal circuit models for learning. Physical circuits require safe voltage limits, correct meter placement, and teacher or lab guidance.
Ohm’s Law Lab Simulator connects circuit controls, meter readings, lamp brightness, equations, and graphing so learners see why current changes when voltage or resistance changes.
Set supply voltage, R1, R2, single, series, parallel, or unknown resistance mode, then connect or remove the ammeter, voltmeter, and bulb.
Record readings or generate a voltage sweep, then use Ohm’s Law Lab Simulator to compare the data table, straight-line V-I graph, and resistance estimate.
Use this Ohm’s Law Lab Simulator guide to connect voltage, current, resistance, series circuits, parallel circuits, and unknown resistance measurement.
Choose a voltage, resistor values, and connection mode. Keep meters connected when you want to read current and voltage directly.
Change voltage or resistance and click record data. The table stores voltage, current, and calculated resistance for comparison.
Use the V-I graph and unknown resistance mode to see that R = V ÷ I and that resistance is the slope when voltage is plotted against current.
For lab reports, describe which variable changed and which variable stayed constant.
