    I have some resistors, well it lookjs just like it with the color codes, but
    instead of them being light brown they are light blue and it do not have
    the silver or gold code at the end.

    Any one know what they are ?

    thank you
  2. Resistors maybe ?

    They're probably "precision" resistors, metal film or wire-wound.
    They have a little different color code, which I don't know
    very well, except that there are 3 digits plus multiplier, and
    they don't use gold (5%) or silver (10%) for the tolerance,
    since they're typically 1% or better. I don't know what color
    band to look for for that one.

    And there's always the ol' reliable ohmmeter. :)

    Good Luck!
  4. If they were red (2) yellow (4) white (9) brown (1 trailing zero)
    brown (1%) it would be a 2490 1% resistor.
