🧪 Engineering Electrical Engineering Simulation
Build a resistor network with a source, series resistance and a parallel branch, then watch its live Thévenin equivalent (Vth, Rth) reduce to a single source and resistor. Sweep the load and find the maximum-power-transfer point.
This simulator builds a real resistor network — a DC source Vs with series resistance R1 feeding a node shared by a parallel resistor R2 and a load RL — and solves it with true nodal analysis. Beside it, a second 3D circuit shows the network's live Thévenin equivalent: a single source Vth in series with a single resistor Rth. Drag any component's value and watch animated current particles flow through both circuits at matching speed, because both deliver the exact same current and power to the load — that identity is the Thévenin theorem in action. A live power-vs-load-resistance chart and a one-click "RL = Rth" button let you find and verify the maximum-power-transfer point for yourself.
This simulation demonstrates basic electrical circuit design and analysis. Users will manipulate components like resistors, capacitors, and inductors to build circuits and observe their behavior under various conditions.
