    Hi guys, im having a problem whit this resistance notation.
    for instance I know that 1k ohms mean 1000 ohms. but what does 1k5 ohms mean? what is with the 5 there:confused:?
    I'll appreciate any help.

    That is a 1500 ohm resistor, or 1.5K. The 1k5 form insures that the decimal point gets strongly indicated for less ambiguity. With faint print, it's hard to tell 1.5K from 15K.

    Hello,

    beenthere is right.
    You can also see an R or M between the numbers:
