- Q: Could someone tell if if I translated this paragraph correctly? Does it sound grammatically or stylistically good? The last employee leaving the premises must switch off the light and electrical equipment (except those that must run around the clock).
- Light should be lights, since I'm sure there are more than one. Run around is somewhat confusing. Because it sounds like the phrasal verb to run around, as in running around the house for example. Maybe say in the parentheses (except those that must remain on continuously) .
- Q: I'm a student looking for things that are involved in R and D aside from Scopes, Logic and Spectrum analyzers, Signal and Waveform generators and VNAs. Things outside of what Tektronix, Agilent and Lecroy would be involved with.
- Check out semiconductor manufacturing equipment at Applied Material, KLA-TENCOR, etc. Check out semiconductor test equipment at Teradyne, Credence, Advantest, etc.
- Q: I think that I might have opened a portal into another world. Yesterday I heard a recording off of the internet that didn't exist! Weird. Also, I have been hearing voices and sounds coming from the room where I think that the portal was opened. I am so freaked out. I have a lot of excess electrical equipment in this room and I feel a little bit uncomfortable with that. I'm wondering if the equipment is making me feel weird too. Does anyone have a similar experience? What should I do? I don't want to hang out with spirits!

- Q: hey yahoos , i just graduated this december on the 22nd with a degree in Electrical and Computer engineering . Apart from the fact that i graduated with a decent gpa ( not that great ) i have no idea why i chose that major or what kind of a job i should be looking for . I didn't have an internship , because of the pressure i was getting from my family which cooked my brain , and i'd rather Not do anything due to pressure than do Anything on my own. I have lost 75% of my motivation already and currently my only motivation is to buy some nice Gadgets, other than that , i don't know :( . , i was wondering if anyone could just advice me anything as if to what kind of a job should i be looking for in this field. What does it even mean by the term junior engineer. , Does anyone know if it's any good to learn 80% of electrical stuff and 20% of computer stuff. Is there a job market for that ? i am looking for a job in new york city itself . i don't have any more characters .:-(

- Q: I'm doing research for a project and am having a hard time nailing this one down. On that same note, what is a panel in the electrical engineering realm?
- Well, often Hardware and Software are used to distinguish between those who design circuits and those who write code. This distinction is necessary because many colleges still include both hardware and software as Electrical Engineering degrees. In a more concrete sense, hardware is the wires, IC's resistors, capacitors, etc. that make up a circuit. The only applicable meaning of Panel I can think of is a distribution panel, which is a box of fuses or circuit-breakers (like the fuse box in your basement).
- Q: I just got a cpu cooling system (fan/heat sinc) the fan stopped working, ive blown it out and it still will not work. I dont feel the need to replace a brand new fan. Any ideas as to what went wrong with it?
- Since it's a brand new fan, that's all the more reason to look into replacing it. See what kind of warranty you've got with it, or just take it back. For all we know, it could have been a dud straight from the factory.
- Q: i am attending college in the fall, actually school starts on the 21st, and my major will be in electrical engineering, i was just fishing around and wondered if anyone could give me, in a nutshell, the basics of this field. since i have already chosen this as my major I do know a little, enough to choose it as my major. i just wanted to know what I might not already know. Give the names of specific jobs that would be of interest after graduation also, if you know any. Thanks!
- Galactic man already gave it all but I just wanted to wish you good luck in your studies. I just became a junior and I'm majoring in EE as well. I wouldn't suggest keeping a certain EE job in mind since you're just starting out. You really won't find what you like until you actually start taking the classes and doing some co-op/internships (if your school has a program like that).
- Q: Hi. I have bought a kiln from Germany which is compatible with our electrical currents here in the UK - that much I know. It is a small kiln and can be used with just ordinary household electric. However, the electric lead is much thicker than the ordinary leads on my other electrical equipment. Is this just for added safety or what? I want to cut off the German plug and put on an English plug so I need to be sure this is ok. Help from a qualified electrician would be preferable if possible please. Thanks so much.
- The heavier wire is to prevent overheating. Cut off plug and wire as normal. Live to the right, Neutral to the left and Earth to the front pin. Luck.
- Q: I suspect my house electrical ground isn't working and had suffered equipment loss due to loss thunder strike.
- If the Lightning is hitting your house then you need to call in a profesional for insurance reasons. If it is hitting elsewhere and causing damage through you electrical lines or through your grounding system then you need to look into surge suppresion for your system.
- Q: Dose that means amount of joules of energy consumed in 1 sec or an hour.
- watt n. Electricity ( Abbr. W ) An International System unit of power equal to one Symbol W. The SI unit of power, defined as a power of one joule per second.
