Today's lab

Sorry I forgot to put this up earlier ...

Today, you'll explore RC circuits, which we covered last week and will come back to next week when we discuss ac circuits and audio filters.


Before you do the lab, however, I'd like you to explore this applet on circuit construction. There are no real instructions, just spend 10-15 minutes constructing different circuits to get a feeling for how things work. Of particular interest is the 'grab bag,' from which you can choose various household items and try to run current through them. Too much current, and you will start a little virtual fire ...
