Q:I have been trying my best to put some few things together as per building electronics and electrical equipment but i really lack circuit diagrams that can put me through. i presntly need a circuit diagram of an inverter with atleast 20kVA output.

pspice

Q:CFL LED luminaires

E-Bay -Business Industrial-Electrical Test Equipment

Q:I cannot see that a electrode would be useful in a generator, is there a way?

According to Wikipedia: An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum). There is an example of an electrode used in generators, and all industrial/commercial electrical systems. It is called a grounding electrode. It is a metallic rod that is driven deep in to the dirt, to establish a contact with the background Earth voltage. Is the dirt a nonmetallic part of the circuit? Well, dirt often does contain metals in it, but it isn't dominantly metal, so it still is considered non-metallic. And we normally hope that the dirt isn't part of the circuit, but there is a chance that it can become part of the circuit, and that is generally why grounding electrodes are installed. The grounding electrode doesn't really play an active role in the operation of any of the electrical equipment. It is more of a safety feature, as a JUST IN CASE the insulation on the live wire fails. Suppose the live wire insulation fails, and the live wire contacts the metal structure of a device (that isn't intended to play an electrical role), and you as a human victim touch that metal structure. You are also standing on the ground, and the natural path of electric current from the metal structure to the ground is through your body. Unless of course, a better path is established in advance. And that is what a grounding electrode, and the rest of the grounding system does. It establishes electrical continuity with all metals that aren't intended to be electrically involved, so that any failure of the live wire will trip the circuit breaker before there is a chance that the human gets injured.

Q:Also, do students studying to become either one of these need to study things like how to program an java and stuff?

I am studying Mechatronic it's a mix of both. You need C for sure as an electrical engineer.

Q:If it is, why?

A house is usually grounded through its piping systems that have generous contact with the damp earth, resulting in negligible resistance. An AC circuit alternately pushes electrons into the earth and draws them back out (60 times a second) for each separate phase similar to the power generation station. Electrons need not travel from power station to house and back full cycle. A separate ground wire (cable) would be required if the earth's resistance resulted in appreciable power losses.

Q:I dont understand how charged particles in the sky would effect the electrical system down here.

A coronal mass ejection has it's own magnetic field. If one were to hit the Earth head on the magnetic field with interact and disrupt the Earth's own magnetic field and allow some of the high energy charged particles through to the surface. As modern electronics become more advanced and miniaturized they also become far more susceptible to high energy ionizing radiation. To those who say it couldn't happen: it already has. Part of the Canadian power grid was taken down by a relatively mild solar storm back in '89.

Q:i dont understand this, every surge protector claims to protect phone lines from surges but why?

Because DLS and phone lines operate on voltages and currents and are susceptible to lags/spikes. GL

Q:If I decide to choose electrical engineering as my college major what would I be doing on a regular basis for my job?

Shelly answered pretty well but there's sooooo many fields you can go into, ESPECIALLY if you get an education in Mechanical Engineering too. I'm going into Electrical Engineering at ECE Illinois, possibly the best school ever created. My (dream) career is working at the Department of Defense for the advancement of science and technology, hopefully more based towards making everyday life easier, alternative energy, and warfare. There are A LOT of careers you can get out of it, like shelly showed, but more. yeah, you just got excited didn't you?

Q:I am studying in college to become an electrical engineer but there is one problem, i'm almost clueless about what i'll do once i graduate. like at what kind of companies and places will i work at? what will i be doing? whats it like to be an engineer? what will be my dutys?. and also how much does an engineer (more specifically the kind in my field) earn? really need to know this. thanks

I okorder

Q:construction, agricultural, forestry, medical, electrical HVAC etcwhat it will be the best name for a business that it will supply some agency with all kind of equipment ( for all possible industries and activities)

how about Workers Supply Unlimited?
