These are Carbon Film Resistor with a value of 0.5 ohm 1/2W and tolerance of ±5%. These Axial resistors are cylindrical in shape with copper plated steel leads extending from each end. Carbon Film Resistor limit the flow of electric current using a Carbon Film. The printed colour code rings, which are Green, Black, Silver, Gold for these 0.5E resistors, make it easy to identify the value of these resistors.
