Abstract Properties of electric circuits such as current, potential, resistance and the relationships between them are often taught using a water analogy. Water circuits provide an excellent comparison to simple electric circuits, but few students have experience with fluid dynamics. This lab allows a hands-on investigation of water flow: including current, pressure and resistance, in series and parallel arrangements, which can be related to electric current, potential and electric resistance. Appropriate Levels Time Required Materials Additional flowmeters can be purchased as Catalog # CNS-204 for $28.50 each. |
