WebApr 20, 2016 · If you put a resistor (say for an LED) on the positive cable then a short of the wire to the chassis will draw limited current. If you put the resistor on the return wire then a short to the chassis would blow a fuse or burn the wire up if it is not fused. A short on the return wire to the chassis will have almost no effect. Share Cite Follow WebApr 21, 2024 · Those resistors have power ratings between ⅛ watt up to only 5-10 watts for the very largest. To get an idea of what kind of power rating this resistor might need for the task of braking, imagine a steel flywheel with a diameter of 3.3 feet (1 m) and a mass of 330 lbs (150 kg), rotating at 250 rpm. We wish to slow this down to a stop in 3 ...
