FAQ

I am gonna graduate in may with a 2 year degree which would make me a Electronics tech. I already was offered a job with Intell and i plan to work there while i get my bachlor. Is there i difference in the 2? and also Intell offered me 52k to start as a tech, is that good? and how much can i expect to make once i get my 4 year degree? thx

There really isn't a great deal of difference. In common usage 'Electrical Engineering' tends to imply high power systems while 'Electronics Engineering' implies lower power (signal processing) levels. But they're really about the same. And 52K is a fairly good salary. The average young engineer out of college makes about 50K to 60K. I believe the median for EE's today is around 70K to 90K. Doug

Have a neighbor that is selling his van to an 80 yr old man. The van has serious electrical issues that go off and on. Just so happens it was working right when the buyer drove it. But almost everything in the dash goes on and off. Mostly it stays off. Is it legal for the seller to not be honest?

No state has any return period for a private party vehicle sale. None. Not 3 days, 3 hours, 3 minutes, etc. If return periods existed on vehicle sales, we'd have people buying convertibles on Friday, returning them on Monday. If the 80-year old man did not have the van inspected by a mechanic beforehand, it's his loss. Any used vehicle transaction is as is unless noted to the contrary in writing. The seller doesn't have to say anything about the condition, and anything said is called puffery and holds no water in court. However, yes, karma will come around and kick this guy in the nutsack. **ADD -- I lived in TX and was in the business for awhile. No, it is not illegal for the seller to not disclose issues. The ONLY thing would be if the seller (private or dealer) did not disclose a salvage-branded title.

E-Bay -Business Industrial-Electrical Test Equipment

A. Identify only the primary source of electrical energy for the equipment or circuits in question.B. Enable backup energy sources, such as generators and batteriesC. Make sure all workers are safe and accounted for before equipment and circuits are unlocked and turned back onD. Avoid testing equipment and circuitry to ensure they are de-energized

picked B and got it wrong. :( its either D or C

Ever tried it on a LG Vu? Also Is that liquid spray safe?Which one is better invisbleshield or BodyGuardz?

As long as you follow the instructions, the liquid isn't harmful at all. Clear films are way better than silicone cases in my opinion.

exactly 5 min later:a- Would it damage the power grid?b-Would sudden surge after 5 min create even a bigger loss in energy than what was saved in that 5 min period??I am not an electrical engineer? I keep hearing that sometimes turning off an energy source for short term does not really save any energy? Is that true?Thanks alot.Could you help me with these 2 points?

Yes, in this extreme case, it may damage (BOE calculation: 2 million x ~500 watts: ~1 billion watt) if they are on single grid. In many of equipment (motorized) start-up losses are significant. So, you may end-up with little saving and a big grid failure. But if you leave aside such extreme situations, it is always good to turn off electrical equipments even for a short gap. And just to add, beware of leaking currents (e.g. not disconnecting appliances from the power plug) which are bigger concern.

Do they actually build stuff or just wire them? I know this is probably a stupid question.

It certainly does not. There is a big difference between an electrical engineer and an electrician. An electrical engineer may well have a 4 year degree course to complete. Such a course will have a high Mathematical content. Electricians do not follow such a rigorous course and will be more hands on. Not a stupid question !

i have problem with my home electrical wiring. the negative and ground pin is live with current even when the power is switched off and when switched on all the three pins are live and most of my electrical equipments are not working. please help?

Wow. It sounds as though you have lost your neutral and have what is called multiwire circuits in your house. Basically what is happening is you have 120 Volts on both the hot and the neutral/ground of your house. If you most of your equipment isn't working, you really have an issue you need to get looked at. Obviously I'm not standing in your house with a volt meter in my hand so I'm taking your word that the neutral and ground have volts, not current, on them. But if what you say is true then this is the most likely scenario. I strongly recommend you get a professional there quickly.
