08-18 Polarization Solution

  • 0:00 - 0:04
    Well, these negative charges all want to get as close to the positive charges they possibly can--
  • 0:04 - 0:10
    which means all packing in to this one tiny little tip, which means the concentration will be higher.
  • 0:10 - 0:15
    This will turn out to be very important when we design a tool to save our buildings
  • 0:15 - 0:21
    from lightning strikes, and this is something that some people call the effect of points,
  • 0:21 - 0:25
    mainly that pointed objects tend to have higher concentrations of negative charge
  • 0:25 - 0:30
    accumulating in them in these situations than rounder objects or flat objects,
  • 0:30 - 0:33
    but there's still huge question to be answered--namely, where did this guy come from,
  • 0:33 - 0:36
    how do we get a positively charge object to begin with.
  • 0:36 - 0:41
    Far all we've seen are how an object can become polarized, how the charges can separate.
  • 0:41 -
    I want to know how to get a charge object.
