Q:Hi i'm 13 years old and i'm always getting tired. for example every day i come home from school i go straight to sleep and i don't know why . This dident always happen till i got to 6th grade. And when i'm at my friends i get so tired and want to go to sleep but i don't know why either ? Please help me and tell me hy im getting so tired and sleepy now and days ?
You may be starting puberty, and that would make this normal.
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:I am currently going to school to study Engineering. I want to become an Electrical Engineer, but recently, I've heard about Electronics Engineering. I did telecommunications in the US military and dealt with small circuits and RF communications equipment. This all falls under Electronics Engineering.I've been trying to find more info on Electronics Engineering, but can't seem to find if it is a separate degree program from Electrical Engineering.My school only lists:Electrical Engineering Computer ScienceElectrical Engineering Computer Sci - Materials Sci EngineeringElectrical Engineering Computer Sci - Nuclear EngineeringHow would I go about becoming an Electronics Engineer?
Yes, those majors ARE separate !!!!! Electrical deals with applications of electricity does the actual work (like a drill or skil-saw). Electronic deals with applications of electricity activating other parts to do the work (like a stereo or TV). The subjects are related, but the majors are different. You will need to contact different schools until you find one that offers electronic engineering!! (I currently .no pun intended.don't know which schools to reccomend.
Q:I want to open a electrical contracting business down in Brisbane or Sydney after i have done my apprenticeship and had a thew years of experience I'm 16(Australia).Possibly even higher a thew lecky and also sell stuff like inverters etc. electrical equipment.The business would service the commercial side more then the domestic side.would this be a viable business or not.and would it be possible to make any money out of this to look after my family and look after my own family. Perhaps a couple hundred thousand a yearor would it be better to just go to the mines By the way i do study business organization and management plus economics so i have a general idea of what would be required like a very detailed business plan etc.
YES! 1%inspiration and 99% perspiration
Q:I was wondering, if everyone on earth was to disappear and there was no one to work the electrical grid, how long would it take for 1] The electrical power lines themselves to decay?2] The electrical substations to break down?3] The transformer units to break down?4] Any other electrical equipment to break [such as those boxes on the power lines, as well as ANY other piece of equipment on the electric grid]?P.S- Don't give how long it would take for the power stations to stop running, I already know that. Just answer the four questions I asked.
The lines are mostly copper or aluminum for the wires themselves. The towers are steel. They would last for decades easily. But lines that run from transformers to homes or neighborhoods could fail earlier. Look at what happens with ice storms in New England. Substations and transformers would last quite long also. But the power stations would last for anywhere from hours to weeks, depending on the degree of automation, and on chance. .
Q:A.neutralB.groundC.short circuitD.load
Voltage in the US is 110-120 volts while in other countries it is 220-240 volts. if you have a 110-120 volt appliance, you need a step-up transformer (110 to 220)before you could use it in a 220 volt power supply.
Q:a. nuderwriters laboratories b. national fire protection association c. national eletrical contractors association d. institute of electrical and electronics engineers
Think logical, and what each organization does or stands for. Good luck.
Q:I opened up my mouse, and im currently using it without the top, because the left click on the mouse is only working about 1 in every 50 or so clicks with the shell on it.Is there a way I can make the click work again with the shell on or do I simply have to buy a new mouse?
You might be better off buying a new mouse. There are some out there that are dirt cheap. You can try cleaning the gunk out of it, if there is any noticeable. I bought an optical mouse 5 years ago for 20 bucks. It still works perfectly.
Q:I am planning to buy a big guitar amp from america and you dont want to mess around with something as powerful as that so i want to know is there suitable adapters out there for such a job? because i heard that some electrical equipment from America will eventually burn out if you use it in Ireland!!help!?!?!
it can be converted with the right parts .
Q:I have a 650VA UPS with a 7Ah battery. It states it can run a device up to 400W, but it doesn't, it tends to overload. It's not faulty, because it works with an older computer, but it doesn't work with mine.Would it help if I switched the 7Ah battery to a 12Ah battery?
