LEDs



Anyone knows where i can get white colour LED lights which looks like these

connecting a LED light isn't that easy. i just blow 2 LED while testing it. Thats because i dint know that i'm suppose to use resistors with them. I remember doin all these in Kemahiran Hidup back in lower secondary, but putting it to practice and doin all these yourself is not easy.

All i wan to do is to connect 3 LED with batteries and i have to think bout all these factors gosh! so mah fan la)

1. How much voltage can a LED withstand
2. How much voltage of battery is required
3. What value of resistors do i need to use if i want to connect the resistors in series with 3 LED? (ohms law)

someone pls help me! any e & e engineers?
