Q:I'm currently doing a 3 year advanced diploma for electronics engineering program. However, I don't feel it could really lead to much possibilities. What do people think?Are there any electronics engineers here in the room?? If so, what challenges do you face??

It's pretty booming right now, and probably will be for the next couple of decades at least. As far as possibilities go, what are you looking for? Some EE's start their own companies and make millions. It's as much as what you make of things as it is about hopping on the right train to take you where you want to go. The downside of engineering has to be the pressure and the deadlines. Marketing and money drive engineering. And the market doesn't want to wait forever for the next gismo. Your design has to be finished by a certain time or else the whole bridge project gets held up, etc.

Q:Can we use land line phone to control houshold electrical equipments. Is the techonology available. I am asking in sense how we use IVR when we call a bank, can we have someting in similar lines. For example, switing on a microwave at home before i leave office.

The answer is a qualified yes. You can connect your lights and appliances to X10-based switches and dimmers, and use the X10 Telephone Responder to control them remotely by phone. This will not allow you to turn on a microwave, because microwaves require their buttons to be pushed. But you could control lights, appliances and HVAC remotely with the right X10 receivers connected. See the links below for some phone-based controllers.

Q:Do electronic engineers make audio equipment like headphones, amps, and speakers? And do you learn this in engineering schools in college?

All by Electrical Engineers!

Q:if you have worked in engineering consultancy, can you please tell me what are the typical projects you take and what exactly you do to help different firmswhy cant the firms do that stuff themselves , why do they need you badly ?

I do electrical engineering and do consulting for companies for the design of electrical systems of new plants. What my company and I do is to get the general power requirements for a large building or factory and specify what transformers, wiring, fusing, lighting, and power distribution methods they will need. Because of my education and my experience, I can provide a customer with the correct power and wiring specifications. The companies then can use my specifications to hire large electrical firms to install the electrical equipment and wiring. Firms normally do not do this for themselves because: 1. It is a one-time thing and they would not generally hire some one directly to do this. 2. Many firms cannot legally do this anyway because the state and local municipalities require a state-certified professional engineer and/or engineering company (like me) to design things like this. 3. It would be very costly and inefficient for a company to acquire this capability for a short amount of time. 4. On many types of consultancy, you want to hire another company because you may want a different point of view or perspective on the problem. 5. Many consultants can provide many types of engineering capabilities to bear on a problem, which can be impractical or expensive for companies to hire. Hope this helps Paul

Q:I have some questions about being and working as an electrical engineer. They are kind of random but please answer in as best detail as possible. (career project here)- Where do engineers work? In labs, in offices, or what? Any pictures- What do they wear to work (random, I know)- Do they do research, or just repair electrical equipment and what not?- How would a Ph.D. effect ones career.- Hows does on become a robotics engineer?

yes its a diverse field good for carrier

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

It wouldn't DESTROY the grid, it would trip the circuit. Imagine adding an incredible charge into any circuit what happens to the current? The resistence? The most notable example of this is the event in Quebec in March of 1989.

Q:I just replaced a light fixture in an apartment complex.I discovered that the bonehead that did the install did not run an equiptment ground when he installed the entire circuit that the light is ran off of (dumb a**!!!!!!!!)Does anyone know if it would be up to code if I where to just drive an 8 ft. ground rod and ground the fixture/entire circuit off of the rod?I have looked everywhere.Cannot find anything in code books.If someone knows where this is in NEC, please include the location.Anybody have any input?

As mentioned the box may be grounded and you cannot see it. If it is not then you must ground it. There is code that will tell you the gauge of the wire that you must use for each circuit. The new code indicates that you do not use a ground rod, but a ground plate. That plate must be buried deep enough that it is in damp soil or it will not work. I am not familiar with the plates, but with the ground rods you need to have more than one and they have to be separated. I have attached a link to the city of Concord code.

Q:a small fire that is at the outlet

Unplug it from a distance and then throw tons of baking soda or flour on it until the fire is smothered.

Q:Any tips for a rock band that will be playing shows in the next month or so? Set-up, breakdown of equipment, working the crowd, preperation, etc?

Learn to put up and break down your equipment quickly. I've seen a drummer take 30 minutes to set up the most basic of drum sets when the set was brought in. Have backups for your guitars and electrical equipment. A broken string on a guitar is a 15 minute pause on your set (experienced that from the same band that took that long on the drum set) to fix it. Ignore the crowd if you think they are bored (in music videos those crowds are paid to be all festive, but they are no where near that in real life). If they aren't paying attention to you, you can forget the onstage talk and sing alongs. Ignore the drunks (talk with the manager before hand on having the manager remove the noisy drunks). Have your merchandise (same band above forgot their stuff and I wanted a CD)!
