duction Circuitry-the sub-field of physics that focusses on the flow of electrons through networks of metallic wires and the functions that different circuits perform-is important to many areas of engineering from designing circuit boards in computers and calculators to designing the electrical wiring in a house. Furthermore, we can extend the ideas of circuits and electricity to the flow of charged ions in fluids which can lead us to many insights about biological systems. In this week's lab, your task will be to use the ideas of circuits and electricity to model the behavior of a biological neuron. This pre-lab is designed to help introduce you to the ideas of simple circuits in the context of typical electrical circuits if you have not yet encountered these in class and to prepare you to extend these ideas to a more complex system. Plan on spending roughly 45 minutes on this. You will have an opportunity in lab to check your results with your group members and your TA. Getting Set Up This pre-lab make
