I've only taken one introductory class to DC circuits where we learned Ohms law and series parallel combined circuits. Now I'm in an introductory class to AC circuits and last night's entire lecture (first day of the semester) was just over my head.
We didn't go over any fundamental concepts about HOW any of these things work, we just started talking about capacitance, and peak-to-peak voltage. I don't even understand how a voltage source that switches polarity produces a sine wave through time. Why are we even talking about "through time" suddenly? How does the voltage alternate in polarity?
We also talked about degrees on a circle and radians, I'm just confused :(
Any help is appreciated!
