I just wanted to say that Circuits are fun. Also, I wanted to ask about your experience with electronics and stuff like that. My Physics class just finished our 1 week Circuits over view...

That is pretty funny....my teacher wouldn't let us do that, but one kid tried to.

Circuits are fun, not calculating all those things with them. I meant to say that making them, and working with the parts are fun. I hate that algebra crap too...

Once you convert everything to phasors though, AC's as straightforeward as DC.

I do believe phasors are simply r exp(iφ) as a means of representing complex numbers. I've never used the term myself.

Lessee, blew two fuses on my multimeter, blew a capacitor (lots of smelly smoke), blew a lightbulb, and melted a dent in the radiator with my soldering iron. No fires, though.
Oh, and something weird happened with my induction coil, but I'm not sure if that was my fault.
Also, I didn't find converting to phasors terribly helpful. Even with phasors you get complex factors everywhere. Ick.

which means that you take the equation of the Voltage for an AC circuit which will be described as a sinusoidal wave

V = 50cos(2000t -pie/10) per say, where t is the time variable. This equation describes how the voltage changes over time. But how do you deal with solving circuits with a voltage that changes over time? You use phasors, which is like using a different coordinate system which separates the equation into real and imaginary numbers. So that, if we describe the generic voltage equation as:

V(t)=Vpn*cos(ωt + φ) where Vpn = amplitude, ω=angular frequency, and φ = phase shift, then we can also describe this as V(t) = Vpn*e^jωt *e^jφ Which means that we can take the real number of that equation which is just Vpn*e^jωt and deal only with it in the calculations, then we'll obtain all real values for the circuit, which is really the only things we're interested in. If we were to take the imaginary part of the equation then we'll get back the imaginary values for the circuit. I don't remember what the imaginary number means exactly, I shall have to look it up and get back to you.

All you're doing is taking the imaginary number out, and dealing with real numbers, as well you are also simplifying your calculations. Phasors are just another coordinate system which you can transfer your cos equations to.

im not so good in circuits sweatdrop

i preferr (sp?) energy and forces

i just keep forgetting which symbol means what sweatdrop

i know the basics but thats it (well, thats probably because im in year 10)

so is the general consensus then that makining circuits=fun while calculating circuits=not fun ?

Anything that raises the potential (sorry for the pun) for electrocution is fun; ergo, since circuits are more likely to electrocute you, they are fun.

On the other hand, calculations do not lead to electrocution (at least not directly), and are can get very tedious and repetitive and tedious. Not fun.

Ouch. Was that one intentional?
I guess I ought to resist making bad puns so often. wink

Thats true. One kid almost switched from DC to AC. Since we weren't playing with coils or anything that day, it probably would've burned down the whole school. *fun*
