Yeah that is why I made the edit. Sorry, too much going on in my head right now. I had that problem first last night then the professor corrected me. Assuming my lab partner took the right reading for voltage on the resistor I have V = 7.25mV.
Ip = Vp-p/2R = 244.9E-6 A
I thought that I was supposed to calculate the current? http://utdallas.edu/~dodge/EE1202/lab5.pdf Top of page 7.
Not sure what I should be seeing across the resistor. I don't understand AC circuits that well. Since it is in series the voltage across the resistor and the inductor must equal the...
okay I found my mistake. this guy in my class keeps changing my ti-83's notation to eng from normal and i miss the E's half the time. I get what you get now (now being paying attention to the Es lol)
So if the measured values look wrong should I go into the lab and remeasure?
Okie doke, phase...
"Well, it depends upon what it is you're trying to calculate. Make a clear statement of what it is you're trying to determine. If it's the magnitude of the current flowing through the resistor, then Ip = Vp/R, or Ipp = Vpp/R, where both Vp and Vpp are measured across R."
I'm assuming it's Ip...
Edited my post, I didn't mean "current voltage" I was typing "voltage lag current" but added a current in front of voltage.
As for picking "p-p" or "p" it was just a type-o going to fix that too.
"Also, if I go by the 5Vpp @1KHz source and the given component values, the magnitude of the...
Homework Statement
Time-domain expression for i(t), based on measures above:
Time-domain expression for i(t), based on measured R and L:
Vp-p on 16Ω resistor: 7.25mV "measured above"
Ip-p for resistor: 0.676mA "measure above"
Ip for resistor: .338mA "measured above"
R: 14.8Ω L: 10.1mH...
Ah, that link helped quite a bit. I was trying to wrap my head around that.
Also, I can't believe I didn't think of oil being used to break the arc by activating a mechanical device. Obviously I was not reading or thinking very critically this morning.
But dang those breakers can get massive.
Considering we are way off topic now anyway this is a good time to ask:
I was skimming over the breaker article on Wikipedia and I saw that it said something about using oil/gas (not natural gas obv) to break the arc. Doesn't that seem a bit insane. Aren't all oils flammable?
Thanks michael83 I subscribed to that guy.
As for why do we need all those things its essentially to scale down the power from the grid to be appropriate for the motors right? I didn't know off hand the function of any of those objects (except the transformer).
While I don't know what all of it means the idea that your are creating something like that makes me extremely jealous! haha

And as for the maths things, I think it has to do with:
Sciences - physics, chemistry, biology, etc
Maths -...
Well, if it seems to be more about which field I want to specialize in I'm pretty sure that's going to be electronics or power engineering. Hopefully power engineering.
Thanks for all the replies!
The uni I will attend is ranked like 50th or so. University of Texas at Dallas. Not bad considering it is only a satellite campus. Then again it was founded by the TI guys so there is a lot of expectations from the school I bet. The JuCo I am at now is nothing special, but I bet it's on par with...
