This microfluidic kit teaches Ohm’s law and the addition of resistors in series and parallel directly observable the visible flow of fluid through microfluidic channels that act as resistors (R). By direct measurement of the flow rate (I) and fluid pressure (P=rho*g*h), the resistance (R) for various configurations of parallel and series circuits can be modeled and determined empirically. It was designed for hands-on learning by discovery but is also suitable for classroom demonstrations. The exhibit will provide others an opportunity to briefly test-drive the microfluidic circuits.
