hi!

does my 10 ohm resistor go after my 5 LED's in series or before my 5 LED's in series ?

resistors are to decrease current and current travels from - to + so isnt it at the end of the series? but most places says the begining

power source : 9 volt

Thanks!

I put it after the leds and it worked like a charm! thanks
You can put it anywhere in the string: At either end, or between any two LEDs. In a series circuit, the current is the same in all components, so order doesn't matter.

Ha ha....a holy hand grenade reference.....awesome!
For the benefit of the OP, it may be as well to make quite clear that this was not meant to be a serious description of LED circuit behaviour. The nature of the original enquiry suggests that this could cause confusion.

For my benefit...could someone please explain what is meant by a holy hand grenade - is this a military in-joke?

It's a reference to "Monty Python and the Holy Grail" and the Holy Hand Grenade of Antioch:
http://en.wikipedia.org/wiki/Holy_Hand_Grenade_of_Antioch

A quote from the text in the link:
Particularly important is the part of counting to three after the pulling of the triggering pin (the surmounted cross), complicated by King Arthur's mental block on counting. The instructions for its use can be found in the (fictitious) Book of Armaments, Chapter 2, verses 9-21, parodying the King James Bible and the "Athanasian Creed".
“...And Saint Attila raised the hand grenade up on high, saying, "O LORD, bless this Thy hand grenade that with it Thou mayest blow Thine enemies to tiny bits, in Thy mercy." And the LORD did grin and the people did feast upon the lambs and sloths and carp and anchovies and orangutans and breakfast cereals, and fruit bats and large chu... [At this point, the friar is urged by Brother Maynard to "skip a bit, brother"]... And the LORD spake, saying, "First shalt thou take out the Holy Pin, then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached, then lobbest thou thy Holy Hand Grenade of Antioch towards thy foe, who being naughty in My sight, shall snuff it." Amen.​
The relevant passage begins at 4:10 in this video:

And it was used to kill that poor little cute white rabbit. <sniff> Of course, later in the script the rabbit said "Tis but a scratch", but time constraints made them take that out.
