Just got a few questions on grounding, I see that on the power source of a ps3 or any electornic device (monitor), on 3 pronged power source, there is a GROUND which screws in to the metal frame of the device, and 2 other wires which are the main power source...what exactly does the grounding wire do? And does it matter where I ground the wires as long as they touch another peiece of metal within the device I am making?
Also, what is the YELLOW part called in this image, and what possibly is its function? Thanks
