WebThis is sometimes intentionally used as a method of hardwiring connections via fuses. ... For example, improperly crimped caps on carbon or metal resistors can loosen and lose contact, and the resistor-to-cap resistance can change the values of the resistor; Surface-mount resistors delaminating where dissimilar materials join, like between the ... WebOct 3, 2024 · The voltage rating on the fuse can be higher than the voltage present on the circuit, but not the other way around. If a 250 V AC fuse is used on a device that uses 120 V AC, there should be no problem. If a 125 V AC fuse is used on a 250 V AC supply, the fuse will be damaged and the likelihood of arching is great when the fuse blows. Another ...
