Re: circuits



Kyle,
I teach very little circuits in my introductory physics courses these days. We have a relatively new applied physics
option in which we teach a lot of electronics.

One idea you might want to consider is introducing more circuits into your introductory physics laboratories.

Some of my favorite ideas on circuits are.

RC time constants: This is an example of rate dependent process which often occur in nature. And can therefore be
justified in a physics course.

Operational amplifiers, particularly integration and differentiation circuits. This can help reinforce some calculus
concepts.

AC circuits and phasors: This is a good example of the power of complex numbers.

Spectral analysis: If done correctly, this can give non-mathematically inclined students a good feel for Fourier
series.

Hope this helps,

Hi;

I wanted to take a quick poll as to exactly how much coverage of electric
circuits you all think is appropriate for the second semester of an algebra
based intro undergrad course? Some of my students (about 1/3) are in two
year technical programs and the review board for those programs (ABET)
suggested we do more in circuits.

I'd also appreciate any suggestions of things to add.
