# AC Circuits Skills List

I stole some ideas from this post from Questions on rubrics.  The comments are really rich too — worth reading.

 AC Circuits 1 2 3 4 5 Skills for Learning 1. Find the main ideas and their relationships in a textbook section 2. Show the relationship between written descriptions, electrical calculations, schematic symbols, and graphs Background 3. Use algebra to prove a point 4. Use technical writing to prove a point 5. Solve phasors 6. Use decibels to prove a point 7. Use Multi-Sim to check your work 8. What happens when you use superposition with AC? Meter 9. Interpret a multimeter DC measurement 10. Interpret a multimeter AC measurement Oscilloscope 11. Set up an oscilloscope 12. Measure frequency on an oscilloscope 13. Interpret an AC-coupled oscilloscope measurement 14.

Take measurements to prove or disprove your predictions about a DC circuit 37. Take measurements to prove or disprove your predictions about an AC circuit 38. Use your measurements and predictions to fix a circuit problem Filters 39. Can a circuit act as a filter?  If so which kind? 40. Find the critical frequencies of a circuit 41. Graph a Bode plot 42. Does a circuit need a filter?  What kind or why not? RLC 43. What will happen in a DC resistor-inductor-capacitor (RLC) circuit? 44. What will happen in an AC resistor-inductor-capacitor (RLC) circuit? Resonance 45. What is a parallel resonant circuit used for? 46. What is a series resonant circuit used for? 47. Find the resonant frequency of a circuit 48. What is resonance?
 Score Means: 1 Understands something about the idea Starting 2 Understands everything about the idea except for that one conceptual error Hm 3 Understands the idea, has trouble applying it Almost 4 Understands and can apply the idea to a familiar problem Good 5 Understands and can apply the idea to a new kind of problem, or combine with other skills in a new way Wow! Circuit Prediction Check Do you know what happens to Voltage ? Current? Resistance/Impedance? Frequency? Power?

1. […] ridiculous.  As you can see, there are way too many — it actually got worse since my first draft.  The list was actually worse before; these guidelines helped me cut it back.  I’m telling […]
