About This Product

Students plug components into the printed layout and follow the current path by eye as they build series, parallel and series-parallel networks, measuring voltages and currents to check Ohm’s law and Kirchhoff’s laws. The capacitor and diode extend the work to RC charging and rectification, and the fuse shows how an overload breaks a circuit. The board is for low-voltage DC only, up to 12V, and must never be connected to mains.

Frequently Asked Questions

What can power the Circuit Board Apparatus STEM Lab?

Four 1.5V AA cells in the rear battery bay, or an external regulated DC supply of 0–12V. It must not be connected to AC mains.
