Making the Circuit

Are you exploring electricty and how it’s used to power all of the indispensable gadgets that surround us? If so, you’re in luck. Paul Falstad has a number of engaging demonstrations that simulate electronic circuits.

If you’re teaching a higher level of Mathematics or Physics or, perhaps, combining both disciplines, Falstad also has other, applet-powered visual resources that’ll help your students envision the concepts you’re discussing.
