    It's a 0.022 Ohm resistor.

    For low value resistors, R is used as the decimal point because a real decimal point is too easy to miss.

    Did it really require a 2.8 MB file to show the needed detail?

    Consider:

    Seems to do the job in well under 100 kB.

    Notice the size of the component compared to the capacitors and the IC below it. That's an indication that it is intended to carry a fair amount of current. It's probably being used as a current sense resistor.

    Looks likes a resistor burned out, possibly in series with the transistor, no way to tell its value unless you remove it and measure it, or look at the coloured rings.

    Thanks for reply

    So the value should be the same even if it burnt ??

    Cant see any colour codes coz all burnt

    Regards

    The value will have probably increased in value or gone open circuit, unless there is another resistor on the pcb thats the same to compare it with, then your doomed...

    Thanks for reply again

    No I cant compare with nothing its only one that big

    So they can increase value or go short?

    Is it worth to get few different values and transistor aswell?

    Regards
