[QUOTE="haywire, post: 475689, member: 16474"] Q. Resistor - what type should I use with my LED? A. Resistors regulate current to keep it to a limit or an acceptable range before it reaches your LED. Current and voltage in a resistor are linearly related (see Ohm's Law.) For this reason it is best to use a current-limiting resistor instead of a voltage-limiting resistor. -- might be pricier... Q. LEDs resistance - what is it and how it behaves. A. Unlike conductor materials, LEDs are semiconductors and don't have one fixed resistance, they have varying resistances. The current flowing in an LED is an exponential function of voltage across the LED. This means that a small change in extra voltage can result in large change of current. Dug up some information on the internet regarding the LEDs [/QUOTE]
