Just started my course, basics help please.

[MrTrance]

Hi, I no throughout the year I will learn all this but could someone help me on the following subjects because I think my tutor expects us to actually no all this.. (he's at his retiring stage):

I don't understand the Earth cable at all (its job etc)

I don't no what a transformer is, or its job, does it work like a fuse?

Also for example, is 230V the current of my house, and whats AMP for, I get confused with volts, ampere and current, It will come to me some day.

By the way no abusive comments please, just joined and only been doing my course for 6 days.

Thanks a lot people,
Micky

I'd also like to know the answer to all of the above...

 

[MrTrance]

Have you also just started your course mate?

hey mickey, try wikipedia
dont worry about not knowing anything just yet

 

[MrTrance]

I have tried, I looked up what an RCD unit was etc, can't find anything on Earthing cables or anything.

 

[montybaber]

Sorry just being silly (please dont take offense ) even though im not all that knowledgable, I'm pretty sure there will be plenty in your shoes at college and it never hurts to read some books on the basics to get you a head start

Hope you forgive my childishness

 

[MrTrance]

Its ok, bit lame I suppose.

 

[montybaber]

Dont be silly, here have a browse of this Basic Electrical Engineering Lessons

We all started somewhere so please don't feel daft - ask away. Any spark who says he knows it all ain't done it all. Everyday is a school day. Best advice I can give is to participate on forums like this and read up as many text books as you can. Knowledge is power!

just taken a look at the link monty should help (brought some memories!!)
the earth is to connect exposed metal to the mass of Earth .the idea is if there was a fault and that metal became live then enough current would flow to trip the fuse/mcb in simple terms.
a transformer is for stepping up or down ac voltage

 

[MrTrance]

Thanks Monty, I shall have a more detailed browse of that when I have more time and patience, looks complicated!

Were can I buy these text books from, I would lend them from the library at college but then my mates might think I'm a geek for wanting to do my best.

What does trip mean and also do u mean the earth just sends the current to the mass of earth so it doesnt do no hard to any objects?

I understand transformer now, thanks mate

 

[wayne]

amazon or ebay,i thought nippers were weened on these websites these days
of course any large bookstore (waterstones) would be able to help

trip as in operate to stop the flow of current



sends the current to the mass of earth so it doesnt do no hard to any objects?

allows a large current to flow so the mcb willtrip

Nothing wrong with that mate!

Welcome to the site, I'm in the same boat as you. Started my 2330 3weeks ago, on day release, but I'm 29.

Loads of info on here and loads of good guys too (and the very occasional female).

 

[MrTrance]

Me, I am always on forums, I own 2 music forums and I have quite a big account on ebay (only 16 though).

Will have a browse on ebay.

this should help matey!

Ground (electricity - Wikipedia, the free encyclopedia)

Transformer - Wikipedia, the free encyclopedia

and just think, if you really get your head down and get get all the work done in advance and get that NVQ3 knocked out asap (start now!) you might be able to get the course done in a shorter time. Thats what i did and got it done in about 2 years.

There will be alot of people in your class that are just there for something to do, dont be one of them!
