It could be real handy because nobody walks around with a digital volt/ohm meter in their pocket everywhere.
The cell phone touch screen depends on electrical capacitance (it actually listens for the “hum” that is all around your skin, called the “skin effect”). The capacitance of where your finger is touching the screen is sensed by the electronics and passes the XY co-ordinates to the OS of hte phone.
Standing the fuse on its end and touching the other end that’s waving around in the air (which you can’t see but the fuse wiggles when they do this) causes the fuse to conduct that skin effect through the fuse when it’s good, and you get no continuity with a bad fuse. Simple, right?
I’ve never tried this, but I imagine putting it in the center of the screen works the best. I won’t go into detail without lots of paper and pencil to draw out what the e-field is doing.
Cool, huh?
There will be a test tomorrow. I hope you kept good notes…
