Is it correct that a uniformly charged conducting plate is made up of two charged conducting sheets, that is, a charged conducting plate consists of four surfaces?

Generally not. But you should give us more specifics for us to understand what you don't understand. – Pygmalion May 16 '12 at 10:15
ok i got it...actually a charged conducting plate is made up of only two surfaces and a charged sheet is considered as a single surface only....earlier i was wrong... – Manisha May 21 '12 at 14:42
I think what you may be getting to is that the charges gather on either side of a metal plate. If we consider a "plate" to have thickness and a "sheet" to be infinitely thin, then this makes sense, although four surfaces makes sense in no scenario. By these definitions a charged "sheet" would have a single plane of charge, and a "plate" would have two planes of charges - on either face. – Alan Rominger Jan 17 '13 at 13:36

For a charged sheet, it is only charge that makes up the thing, there is nothing in between.There is a single layer of charge. But a charged plate has two layers of it. It is better to think like this if you are trying to find out the fields due to them.
