Phasors that aren't quite Impedance yet

A sinusoid is a signal that has the form of the sine or cosine function

This is the most similar font I could find on here to Comic Sans, so the rest of the blog will be written in it, as a form of repentance for not doing the blog on time (it's a sad time writing this on a Tuesday night at 8:53pm, at least I have this glorious coffee, black liquid to warm the soul and lubricate the finger joints that I laboriously strut across this deteriorating keyboard that has served me well for so many years, not like my vagabond work ethic that leads me to abandon classes and projects like so many lost dreams of things that could be or could have been had I only put the time and commitment to them, like basket weaving, or having a relationship with my family, or speaking Spanish better)

Whew, passed out there for a little bit. I hope I didn't write anything embarrassing or permanent on my blog.  Oh. Oh my. Nothing to see here. Onto class things:

Sinusoids and Phasors! They exist.



































































I was somewhat hoping you'd stop reading up there.
Oh well.

Sinusoids can be transformed to phasors.  This is a neat thing.  There's a simple transform between the time and phasor domains.  There's a less simple transform between the time and Laplace domains.  But we can't use phasors for everything, and we can use Laplace for (just about) everything.  It's a tragedy we won't get to Laplace, because the stuff I've been reading out of the textbook is gosh darn neat.
Things to remember:
Inductors voltage lead 90º
Capacitors voltage lag 90º
