A silver coin works on a smartphone, you can use it to open apps and scroll lol it is quite cool I use it as a magic trick with my kids, I have a modern quarter and a '64 quarter so I will use the one that doesn't work then switch to the 64 they are always amazed. Nice way to check for fake silver as well Report this Post to the Staff

Dorado Bedrock of the Community Canada 24885 Posts	Posted 03/10/2018 5:09 pm Conductivity Conductivity defines a material's ability to conduct electricity. Electric current can flow easily through a material with high conductivity. Conductivity is measured in siemens per meter and is often represented using the Greek letter σ. A material such as metal has a high conductivity, while rubber has a very low conductivity. A semiconductor's conductivity is intermediate. Factors such as temperature have a large effect on conductivity. Resistivity is the reciprocal of conductivity so that a material with high conductivity has low resistivity, and a material with high resistance is, by definition, a poor conductor.

Crazyb0 Rest in Peace 10197 Posts	Posted 03/10/2018 6:34 pm Interesting Dorado, then my AA in Electronics Technology kicks in as does 33+ years in electrical services industry, although they still were teaching vacuum tubes when I graduated...aaannndd,... Why then doesn't the high(er?) Conductivity of copper also work as a medium of human body capacitive discharge? IDK the answer either, wonder if it the molecular weight/structure which affects resistance, hence capacitence? Then let's toss out a stinkin zinkin...with the rot, a perfect capacitative discharge of reactionary metals to a acidic medium, ? Is that the secret plot behind keeping them? That the toxic waste of rotting zinkins has attached to the human skin allowing for....touch sscreens? Shhhhhhhh! I'm hunting wabbits! Report this Post to the Staff
