Could anybody describe me difference between I've added and I added?
The key to the difference is "that has present consequences". If you are regarding the event as complete in the past, use "I added"; if you are considering its present relevance (eg the state of whatever you have added to) use "I have added". Note that there may not be any difference in the event: you can describe the same event either way, but you are focussing on different aspects of it. Generally you cannot use the perfect with a explicit time, unless that time is a period which includes the present:
(The * means unacceptable)
To me, the difference between I didn't see him today and I haven't seen him today is that the first implies that the possibility of seeing him is over (perhaps he was only here this morning) whereas the second doesn't. I believe that North American usage is not the same in this regard, though.
I've added is present perfect, while I added is past tense.
Again from Wikipedia
One is a contraction for "I have added" while the other is "I added." The emphasis is in a slightly different place, depending on your usage. We would need a little more context to make any more meaningful comparison.
The format using I added refers to the question: "Who added some exercises to my homework?", and the answer "I did, I added some exercises to your homework." The format using I have added refers to the question: "What have you done to my homework?", to which the answer might be "I have added some exercises to your homework."
I guess we need an exemple:
Your mum gives you homeworks, with many exercices (monday)
then (tuesday) she says: "I have added few exercices Billy"
if she say (tudesday): "I added few exercices" that would means she did it yesterday (monday)
So when she says "I have added few exercices" She uses the present form meaning she is probably asking you to do your homeworks, you are already speaking about homeworks and when you speak you are in the present :)
