Amprobe 660.25-6X32, FUSE, 1/4 AMP

hello this is Gio and today I'd like to talk about fuses specifically how to test whether a fuse is good or bad now I do have a bunch of fuses here they're all basically the same shape these are all four kind of electronic devices this four amp fuse this is a 5 amp fuse fast line this one's also 2 amp fuse is a little smaller than this one there's also these called slow blow fuse which takes more than just an instant instant to blow if if they blow now what fuses do is essentially what a fuses is is a type of resistor and it's a resistor specifically designed as kind of a sacrificial kind of resistor so if in in this case of 4 amp fuse if the current going through here exceeds the 4 amps the the resistor or wire in there will overheat and blow or melt and break and therefore cut off the current and so it there are a sacrificial device and when they're their job is to blow if the current
