16 Exp#3: Linear Circuit Theory and Experiment 1. Introduction The most successful and decisive experimental investigations are closely coupled with theoretical work and/or numerical simulations. Explicit predictions can be tested and compared with measurements (provided we have a mechanism in place for comparing numbers in the first place, of course!), and with computer-based simulations. All three of these approaches have assumptions and simplifications built in, and none of them can claim to give absolute truth in their result. However, when theory and experiment in combination agree sufficiently closely (What does this mean? Defined how?), one can reasonably claim to have a predictive model that can be used in practical scientific and engineering applications. The particular example in this lab is a simple, steady-state circuit, whose properties can readily be predicted, and that can be built and tested quickly. We will build a two-step voltage divider circuit, where a constant DC voltage is divided into two smaller values. Circuits like this can be found embedded in much more complicated ones, and it is very useful to be familiar with this type of operation. First, we will do the theoretical work, then build the physical circuit. Finally, a circuit simulation will be built, tested and applied to the same problem. 2. The two-step voltage divider
