So if a balloon has 3 .5 microculems of charge, what that means is it has a positive charge, and that charge is coming from electrons or protons, or basically an excess of electrons or a deficit of electrons.
00:25
And so because it's based on electrons and protons, we need to know what is the charge of one electron.
00:31
And the charge of one electron is 1 .60 times 10 to the negative 19 coulumes.
00:37
And that's just a constant in the universe.
00:40
And so if one electron is equal to this many coolums, then we're basically looking at how many electrons is equal to 3 .5 microculems.
00:50
But before we solve that, we have to convert 3 .5 microculems is equal to 3 .5 times 10 to the negative 6 coulooms.
01:01
Because micro is times 10 to the negative 6.

So i would do this by setting up a proportion...
