Wednesday's lab: electrical components
UPDATE: I've included another part of the experiment in which you'll learn about the function of photoresistors, and a bonus circuit construction project where you'll build an 'electric eye' circuit if you want some extra points. The files are in the same directory linked below
----------
Wednesday's lab is a simple one on components, designed to introduce current & voltage and operating the lab boxes. Find it here: http://faculty.mint.ua.edu/~pleclair/ph102/Labs/components/ (2 parts, 2 files).
One small warning, of sorts: this lab is not at all as obvious as it seems when you take into account non-idealities of components, sources, and meters. Once you've seen it once, though, it is straightforward. That is part of the point of the lab - how to real components, sources, and meters work, as opposed to the ones in the textbook.
I will probably add a small section to the lab at the end where you will explore photoresistors and LEDs combined to make a simple sensor-actuator setup, just a qualitative thing where you describe what happens. I will post the revised procedure late tonight.
