Maxwell — Javascript Circuit Simulator

Phil Sung <psung@alum.mit.edu>

Maxwell is a simple web-based tool, suitable for educational purposes, that can simulate circuits containing wires, resistors, and fixed voltage sources.

Start

Instructions

1. Build your circuit by dragging circuit elements out of the toolbox (in the top left-hand corner).
2. Add wires by dragging lines between circuit elements.
3. Click on elements and type to change source and resistor values.
4. Click on elements and press Delete to remove them.
5. Drag the multimeter leads to your circuit to measure voltages.

If you find a bug, please tell me about it.
