This interactive Three.js simulation demonstrates Ohm's law in a 3D electrical circuit, showing how voltage and resistance affect current, power, and animated electron flow. Users adjust sliders and toggle power to observe real-time changes in the circuit's behavior. The scene includes 3D models of a battery, resistor, and LED, with WebGL rendering and orbit controls for perspective viewing. The code relies on the Three.js library for 3D scene management and animation, presenting circuit physics through direct manipulation of electrical parameters.
