In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served

Q:how we can design the power rating of any electrical equipment. as per my understanding only way is is to change the resistance of coil( winding if motor, filament if lamp).if it is correct then the equipment will be burn if resistance is low for low power rating. Eg. resistance of filament of 10 w lamp is lower than the resistance of 100 w. generally life of 10 w lamp is higher than 100 w. but in electrical point of view the life of high value of resistance equipment will be higher than the low value value of resistance. means, 10w bulb will glow longer time comparatively 100 w bulb. since 10 w bulb has high resistance , so this bulb's life should be higher than 100w bulb. can anyone explain how to design the power rating of any electrical equipment in line of other electrical parameters.: Most equipment involves loadings on all the materials used and these materials have various load-carrying limitations. Design essentially balances these against each other whereby the materials' limitations often interact on the design. For existing design variation much empirical data and experience data will be available which will accelerate the design process but for a competely new design, the process may be iterative and toward the end may even need several prototypes to be built and tested. You can't merely change the resistance of a winding in a motor and get a higher rating. Things like core flux density and temperature-rise of insulation (affected by cooling, whatever type that may be) must all be checked. Lamp filament resistance is indeed lower for a higher rating but filament surface area (to get the radiation) and temperature will have to be decided which involves knowing and designing how the lamp radiates light and how it is cooled. The lifetime of a bulb can be quite precisely designed in, largely by the design temperature choice.

Q:Do you find batteries die faster than they should, light bulbs flicker or go out too quickly, electrical equipment does werid stuff or dies sooner than it should. I've had some weird experiences with the computer and one small printer ar work. Also, I had a period where remote controled TV's would go on by themselves. I don't have that problem now, though.: there is alot that god will do to help people belive somthing if thats truely what they want to blive i belive if a shirital being is still omn earth other than Gods angles that will never give people supernatual powers i think thant evel can give others pwoers to tell the fucture to do the imposible suck as wich craft God said he would not saport wich craft becousr the evel ones are the ones that give the flesh the powers anf if you belive you have the powers tp do somting enough i think sata will give it to you in away that gives you power that you belive is your own ang will drive you away from God im sorry if you dont belive in God i dont want to push ant thing on to you eather way this it just my beliefe and if the electriity in ones body is chaneled difrent then other its eather that or couse were created difrent then others and its afact every one has a eletric charch that keeps them alive ive never exped this but i belive some have i cant say waether its a gift from satan or how God created you mabe somthing you were exposed to or a defect in the geans when you were born mabe a posative afevct and mabe taking in the eletricity is what keeps some one alive becouse the produce normaly less charge than there body needs its somthin that one day will be studied as it becomes more comon as all thing do or they just die out like spontanios cumbustion did eather so rare it is not studird or just a mith or somthing that is of the past this is just an opinion i have never herd of this but i do know that eletricity is a major part of hat amd mind function and existed sence the begining of the earth and space and was not nvented but descovered i hope this helped feel free to contact me id love to talk futher and here about you experinces thank you and have a nice day

Q:I have some basic questions about SketchUP and AutoCAD.I'm totally new to 3D software and was planning to enroll in an AutoCADcourse before I found SketchUP and found out some self training with thefree tutorials might give me some good handicap before I go to the more advanced stage.My question is : Is it possible to transfer without any issue (bugs, etc.) a 3D file from SketchUP to Autocad and continue the work in AutoCAD, or vice-versa?What would be the best way for someone like me (that knows almost nothing) to get started?andwhat would be the best figures to start drawing for someone who eventually plans to design mainly electrical heavy equipments?Thanks a lot.: Sketchup Vs Sketchup Pro Comparison

Q:I am looking for electrical equipment that are commonly used in industrial plants, power plants or substation. I was hoping anybody here could help me.: motors transformers switchgear motor control centers large breakers molded case circuit breakers disconnect switches load carrying cables signal and control wiring relays terminations etc.

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:I just moved to a house in Vancouver, WA, and am wondering what companies can ship/move a large storage container (like PODs) from Houston, TX to here in WA. I will be doing it within the next month or two, and need a general estimate on how much it is going to be (I can figure that out, just need some websites or company names): google long distance movers you will find many suggest that you get an estimate from several as prices can vary greatly. you will need to estimate how much you need to move. --

Q:I am currently studying electrical engineering in college but Im considering maybe teaching math for a while. But I wanted to ask what the daily routine is like for an electrical engineer at workThank you: There are different types of Electrical Engineering jobs. Could be with:- Civil engineering projects Mechanical engineering projects . Electronic engineering projects Might be an idea to enter industry and perhaps enter teaching at a later date. Not an uncommon route.

Q:I plan to major in electrical engineering. I wanted to know if the stuff I learn there will allow me to do things like fix machines and stuff.I picked this major because I wanted something I can use at home: Yes and no. The basics will be covered in both theory and some lab exercises, but the bulk of what you learn as an electrical engineer, will be power generation/distribution and industrial applications, not domestic. There will remain a whole lot of best practices and regulations electricians know about, but you will have to research on your own if you want to maintain/expand the electrical system in your house. So, yes you will be qualified if you inform yourself about the practicalities, but it won't make you a qualified electrician be default.

Q:how is this possible?: Theoretically, yes they do. Practically, no. If load resistance decreases, V out decreases some, if load resistance increases, V out increases some. All wires have a resistance, even the wires from a supply point to an electrical outlet.

Q:Downstairs 4 outlets and 4 of the lights stopped working. One of the outlets that doesn't work has the top plugin socket working but the bottom one doesn't. Also 2 lights still work even though they are in rooms where the sockets don't work. At the time we did have two computers running from the outlets and maybe some other electrical stuff. When the electrical went out we heard electrical sparking sounds.Then like a couple months later it happened again but upstairs. The lights and outlets stopped working in 2 bedrooms and the bathroom. I don't think we had very much electrical equipment plugged in just maybe a hair straightener.If I reset the breaker the switch will move to where its supposed to be but nothing happens.How much money should I have on hand for the electrician approximately? $200? $1000?: I would start by looking at the outlet where only one of the plugins work. Usually only kitchens are skip wired (2 separate circuits on top and bottom plug). When you had the sparking (short) it probably burnt a wire off.
