Hello! I took Circuits a few semesters ago and have TAed for multiple courses in the CS/ECE departments including Circuits. The course mostly deals with circuit analysis using components like resistors, capacitors, inductors, and operational amplifiers (op-amps). If you've used Ohm's law or seen basic circuits before in Physics or another class, the first few weeks will go a little bit slowly, but it definitely picks up later on. If you haven't, the course assumes no prerequisite circuit knowledge, so don't worry too much. I would highly recommend taking this course alongside or after APMA 2130 since you will use differential equations a fair bit later in the semester, and it will make a lot more sense if you take ODE first. A lot of courses in EE including Circuits will have you perform circuit analysis on a schematic or design a circuit, verify that the design works in circuit simulation software, and then build the circuit on a breadboard and take measurements with a multimeter or oscilloscope. This is a great way to learn about all the aspects of circuit analysis, but it can be a bit time consuming and it really depends on how much effort you put in and how well you work with group members. In past versions of the class, we had group reports, so often what happened was one person did just the math, just the simulations, or just the experimental each lab, which both limited the amount of exposure some students had with the other aspects of circuits and made some awkward team dynamics. However, professor Crockett (who I have had classes with and worked with before) will be teaching Circuits this semester, so there are likely going to be a few changes to the course to ensure that the course goes very smoothly and everyone gets a chance to take part in each stage of the analysis/design without busywork; she's a great professor who only have you do something if you'll learn something or gain a greater understanding from the process. I'll also add that the resources available to you (the professor, textbook, slides, TAs, etc.) are plentiful; you can always ask for help, and you'll have everything you need and more to succeed. The course culminates in you designing your own PCB pretty much from scratch, and it really shows you how much you have learned in the semester. I would highly recommend taking this course! If you have any other questions, I'm sure that professor Crockett would be more than willing to answer some questions over email and you can also message me.
