Brainiac Electric Fence [Virtual Demonstration]

This was a video demo to begin with. So it was half-way virtual already. To maximize its utility, I needed to chop this Brainiac: Science Abuse segment up and intersperse questions. The physics is nice in that it ranges from fundamental up to “beyond the scope of this introductory course”. From conductors and insulators, through series circuits, to R-2R resistor ladders. This is a nice lesson to put near the end of a circuits unit. 

Since I remixed the segment (really just chopped it up), I'm posting this as a Fair Use freebie.
