Thank you!

Pin locations #5, #6, and #7 are labeled as Y, W, and G. Would some please clairfy these? Please note that pint #8 is GND (ground). Thanks again for your help.

I'll add the best way to remember what occurs in each device is our good old pal: ELI the ICE man.

Wonderful! Thank you!

Only $14 to take the exam. Basic electronics knowledge and a few rules and you should be able to get your first license (Technician) without a problem. Once you do, best of luck studying. I would highly recommend the online practice exams (again, QRZ.com has those). As a VE, I would highly...

You don't need to be a member of the ARRL to buy their books. You should be able to look through their online store and buy whatever you want. I would also suggest QRZ.com and their online swapmeet. A lot of good stuff on there, and there's always books and other information being passed around.

Could anyone please provide me with a labeled pin diagram of an 8:1 Mux or list it on here? I have tried searching and haven't had much luck. Thanks for your help.

Yes, it did. Thanks for your help.

Ok. I'm stuck again... Basically we want Ex=0 at some point (P3) on the y-axis. So the point P3 (0,y,0). Taking the two points to get the total E field. ET = E13 + E23. I've got: E13 = 25nC [(0-4)ax + (y+2)ay + (0-7)az ] / (4*pi* 8.854e-12 [(-4)^2 + (y+2)^2 + (-7)^2]^3/2) E23 = 60nC...

It appears I might have been way off base. Reworking a different thought...call off the Help Department (for now). :) Report back in a few...
