A simple way to demonstrate parallel and series circuits.
This parallel and series circuit demonstration can be easily taken apart and reconfigured in a variety of ways to experiment with and observe both parallel and series circuits. This versatile piece of equipment can help students to distinguish between series and parallel circuits and come up with a conceptual and mathematical understanding of how voltage, current, and resistance behave in a series or parallel circuit.
Ordering information: Variable DC power supply (10 V max) required, not included. Includes heavy duty base with 5 bulbs, 8 removable metal bars, and 10 thumb screws.
