1. ### No load transmission line

Homework Statement I was given all the full load stats of a long transmission line(100km) Vs, Is etec and i need to find the N0-load Vr and Is and no load Power consumed Homework Equations Im not entirely sure how to handle this, i would think, sense there is no load Vr and Vs are the...
2. ### Force to g units

alright thats what i thought, i was expecting it to be more complicated
3. ### Force to g units

this problem might be extremly simple but the wording is confusing me b]1. Homework Statement [/b] "What dose that force correspond to in equivalent acceleration in g uints? (9.81 Nt/Kg)" the force i had from the question be fore is 1.8uN (micro) soooo is it asking me how many g's...
4. ### Scaling law for static buoyancy

Im doing this exact same problem in my MEMS class and i have the same issue
5. ### Need Mathematica graphics help

i had to break each element into sections but i manged to do it just using the line graphic, it was a pain the the *** tho
6. ### Need Mathematica graphics help

making the capacitor symbol is really giving me trouble this is what i have Cap1 = Graphics@Line[{{1, 0}, {1, .5}}] gave me a vertical line Cap2 = Graphics@Line[{{0, .25}, {1, .25}}] gave me horizontal line Capleft = Show[Cap1, Cap2] gave me half of the capacitor logo then i rotated that...
7. ### Need Mathematica graphics help

no this is the last hw in a mathematica class. so we need to use it for the whole thing. The other assignments seemed useful but this one one pointless
8. ### Need Mathematica graphics help

several hours later and I've made no progress, i cant even join two lines to make 1 side of the capacitor. If ANYONE has the slightest idea how to help, i really need it
9. ### Need Mathematica graphics help

Homework Statement I need to find a away to make circuit elements (resister capacitor etec) in Mathematica using lines graphic, and im new to this so im not really sure how.......and i need to connect the elements to make a circuit. i think i made a resister Graphics[Line[{{0, 0}...
10. ### Mathematica Hw

Homework Statement Problem 1. Create a program to display a complex number (or a list of complex numbers) as an arrow (or arrows) on the complex plane. i know RandomComplex[] will give me a random complex number, and i know RandomComplex[{1 - I, 1 + I}, 5, WorkingPrecision ->...
11. ### Full wave rectifier/line regulation

i beleive VDC = Vmax-(Vr\2) but im not sure
12. ### Full wave rectifier/line regulation

peak voltage of 12rms is 12square root of 2 so 16.97V and with the 10.9rms --> 15.41
13. ### Full wave rectifier/line regulation

isnt that 2.5V dependent on the diodes in the bridge? we used 1N4002's
14. ### Full wave rectifier/line regulation

ahhhh crap. im starting to think my group did this whole thing wrong. Well ok so +/-10% for a max we supplied 12V+10%- 13.2rms and then for the min 12V-10%-10.9rms We must not have been supplying enough current/voltage for the rectifier to do its job.
15. ### Full wave rectifier/line regulation

our regulator was made with 2 1n750 zener diodes in series both pointing up Rs and the resistive load. . Im thinking we must have been out of the range then
16. ### Full wave rectifier/line regulation

Im Sorry it was the Load regulation I screwed up. Yes we did observe with a oscilloscope For the Load VDC= 12VDC 10ma<IDC< 60ma Load ripple < 50 mV p-p AC Supply 12VRMS +/- 10% 60Hz http://img207.imageshack.us/img207/4391/loadimax.png [Broken] loadmax...
17. ### Full wave rectifier/line regulation

This is more of a lab then a homework Ok, so i had a full wave bridge rectifier w/capacitor hooked up to a power regulator. and i was attempting to perform line regulation- and for a Vmin i should have got around 10.5V but i got 2.4V. Why is that? I think the rectifier stopped rectifying but...
