1.从外观看,此电阻器本体发黑,并且表面破裂.经测量电阻器阻值无穷大,可判定电阻器开路损坏.见附图一.
2.经解剖,电阻器表面涂层松动,内部合金丝成粉化状,棒体有炭黑,从而可判定电阻器是因为大电流通过,造成保护性熔断,如附图二.
根据提供不良电阻器,做相关实验如附图三,四,五.电阻损坏,出现类似不良,电流至少在10A以上.已超出材料承担的电流,可判定为输入端出现异常电流导致电阻损坏

1. Viewed from the outside look, the resistor's body is black, and the surface has rupture. The measured resistor resistance is infinity, according to that can determine the resistor open circuit is damaged. See from the attached figure 1.
2. After anatomised, the surface coating of resistor is loose , and the internal wire is transfered into powder form, there's black carbon on the rod, thus can we judge that large current through the resistor lead to the protective fuse, as the second appended drawing says.
By providing negative resistor, conduct the related experiments as illustrated three, four, five. Resistance damaged causing a similar bad situation, the current is more than 10 A at least.When the current is beyond material's undertaking ,we can make a judgement that the resistance is damaged because of the input abnormal current.
