I already know how to calculate there resistance using the firstthree bands and that the fourth band is the tolerance band but inthe situation with the following resistors the fourth band is blackand I cant find anywhere which states what a black tolerance bandmeans.. I know that it means zero or 1 if its one of the firstthree bands.
So if you could tell me what the tloerance and quality of thefollowing 3 resistors and any other reasons that the resistor shownmay cause errors when used in a circuit (inc maybe the way its beensoldered) it would be great,
