I was having many functional issues with my Comcast high speed internet connection. I removed the splitter(Freq. range 5-1000Mhz. -3.5db)
that feeds one DVD/VCR and the desk top. Connection now direct too wall outlet. Now my connection is great. Question is whats the proper elec. resistance of splitter in question. I measured infinte/open resistance with a fluke 189 through the splitter, if that true how did connection work at all period. Or is DVD/VCR effecting the cable line? I'm I measuring splitter properly?

Recently, NASA conducted the test on scramjets. The jet tested flew at a speed of Mach 10, ie, 10 times the speed of sound.

Can scramjet be made to fly much faster, or is that the maximum limit it can fly at?

I have a full wave bridge rectifier with two capacitors @470ufand 3 resistors in series @ 100, 100 and 1 ohm, can you explain the effect the size of capacitor has on the ripple? and also the effect of the size of the load resistance on the ripple? Thanks

How much math do you need to retain when you graduate from college? does Electrical engineers use all the math skills of calculus 1 2 and 3 and trigonometry and physics?
In school they teach you all that but how much of that do you really use in a job? what are the most common math skills EE use in a job.

I'm asking this because i'm studying EE and I'm in college algebra level now, and I'm thinking how i'm going to retain all this information plus the coming math classes and physics. I would probably retain like 50% of what they teach me.
Does EE use every single thing they teach you in math and physics?

Please Help.

I mean.....can we somehow use a printer cable or some other cable to measure voltages and observe waveforms generated by circuits? If yes, how?
If no...........y not??

half. Then you place the four pieces you now have in a stack and rip the stack in half. If it were physically possible to continue this process of stacking the torn pieces and ripping the stacks apart for 50 times, the stack would have 250 pieces. How high would this stack reach? (Give your answer in meters.)

Hi, I'm a robot "fan". Which means I read Robot magazine, I own and experiment with Lego Mindstorms, and I'm a programmer by trade. I know that one day "Synthotics" (a word I made up) will be a reality. (Synthotics - a branch of robotics specifically concerned with the mimicking of humans; by combining relevant fields of sculpture, animatronics, and traditional robotics) Traditional robotics don’t like to deal with “faking it” where animatronics does. With the marriage of these two we could produce an exciting product. So the question remains, “Why is it taking so long to get a robot girlfriend?”

There is a significant current surge when you first switch on a filament lamp .
what's the theoretical model of this phenomenon ?
I assume that there is a huge different between ac & dc in this case .
some one told me that i should get help from faradic , or this formula : L( di / dt )
Please help me out !
I'm so confused

Somebody said that the place I work was going to be demagnetized.I work at a battery warehouse and all the manufacturing buildings at the main facility are also supposedly set to be demagnetized as well. I know why airplanes and submarines would need to be demagnetized? But what is the purpose of demagnetizing a building? Or is this a false statement on somebody's part. The only thing I can think of is it has something to do with 3-phase current? As far as I know all the PLC's and computers run on AC. I know maintaining DC power for computers and production machines is complicated so probably 3-phase current is being used. I know when I worked at a machine shop the networking running to the CNC lathes would always stop working because the place wasn't grounded properly. Any information would be helpful to me, because, as of now, this makes no sense to me at all.

I am looking for either PVC/ABS or vinyl tubes...of approximately 1/2 I.D., similar to the vinyl/plastic sheaths over bicycle lock chains. They must be fairly transparent/thin, coloured and flexible, and of varying lengths. I am in need of small quantities at first, as testers for my product needs, but will certainly be in need of larger quantities in the future.

I have checked craft stores, hardware suppliers, etc., and have no idea where to procure something that will fulfill these requirements and be readily available without jumping through a lot of hoops.

Tanker trucks (which carry liquid) are always cylindrical. Their cross section is a circle as opposed to normal trucks which have a rectangular cross-section. There must be a real-good reason for this. However, i cannot figure it out.
