It is important to distinguish between actual non linear loads, such as rectifier input supplies, and time varying linear loads. A light bulb is a time varying resistive load, but it is linear (not as w-dude stated). The time constant of the resistance is dependent on the heat capacity of the...

Peng, Nice try, thanks for the effort. w-dude ignores pretty much all facts, and absolutely does not understand the engineering aspects. As you are learning, lack of knowledge has not been a hindrance to him. Soon, he'll be pasting links to a bad antennae ground without having read it...

Why? You never quote reality. You make up numbers. You need to actually read and comprehend, you fail to do this simple thing. REALLY?? NEC says nothing about low impedance connections?? So I guess I can toss out article 250 as well. You know, the article called "grounding and bonding"...

What a poser. What would you be without google and cut and paste?? I guess I should rip up my copies of NEC, specifically articles 280-285? Guess your google search didn't include that, eh?? Try again. This is fun. Ah, almost forgot. This from your link: So much for "all SPD's are...

I have stated that you have no understanding of electricity, that you are an internet poser with no education on the topic. My facts are your posts. Over the years, I've detailed faraday's law of induction, amperes law, mutual and self inductance, time varying magfield based loop area...

As opposed to what the NEC says, what UL says, what every NRTL says. Only you are right. The NFPA does not advertise. Nor do any Nationally Recognized Testing Labs on the planet. All my electrical technicians understand this. Some of the mechanical ones do as well. You do not understand...

For everybody's illumination, I've hilited in red the abysmal errors consistent with someone with no engineering or math education.

I post this for all others. W-dude has no understanding, so can learn nothing. Lightning is but one example, and it is comprised of 4 categories. 1. Direct hit to house. 2. Direct hit to powerlines. 3. Earth strike close to transmission lines. 4. Earth strike close to house. Branch...

Then how can he become the best on this site?? He's not yet #1. jn

Really? So then, Thevenin and Norton got it all wrong?? Perhaps you should google that, then add it to your cut and paste repertoire. You need a basic understanding of current, voltage, and the equivalent circuits. Only you can decide to learn, we can't force feed you. We can laugh at you...

That always depends on the specific devices, so you'd have to take it case by case. It is indeed safe to daisy chain from an electrical point of view. However, it is not a recommended practice. All the ele guys hate to make a Christmas tree out of cords and adapters. But I understand your...

I am also an engineer. I do understand it. Whether or not the settling time differences as a consequence of load impedance variations on a sub wavelength transmission line rise to the level of soundstage disruption (5 to 10 uSec differential ITD) would depend on the ratio of the line impedance...

On a previous reno, I installed 4 boxes around the living room, with conduit dropping to the basement. I spoke to the GC about it, pointed out that the boxes had been mounted FLUSH to the studs such that the rock can be installed without cutouts, as I wanted the boxes for later use. The...

So then, we can all pigpile on you telling you what you should have put in.;) Hope it went well for you. During reno, I put in 9 runs of cat cable (bought 1000 feet), two spare coax, two spare speaker runs, two thermostat spare, two telephone spare, and 4 copper pipe runs for later heating...

Actually, not quite. It is to prevent a potential rise which can damage equipment or endanger human lives. In many cases, it requires engineering to provide a conductive path which does not radiate sufficient time varying magnetic field to destroy anything with a conductive loop. In some...

Electron speed is proportional to current density. For room temp wires, speeds in the mm/sec area are closer. Meters per second would mean the wire is way too hot. The hyperphysics website has a calculator for this. The water example is incorrect. For small loops it will indeed look...

Had you a degree in electrical engineering, as I have, you would know that faraday's law of induction cannot be applied to a dipole antenna of any length. Since you do not, you make glaring errors. You haven't made one statement that would lead anyone to believe that you have any work...

BTW, if anybody has questions about what I've posted, or even what w-dude has posted erroneously, please feel free to ask. I've no problem detailing what I've described. While speedskater has alluded to my writing style has being a really weird mix of things, I find I cannot disagree..:)...

Ummm, because it's apropos?:) Tis only a flesh wound... jn
