All right, so let's say we have two capacitors in parallel, like this, this is c1, this is c2, and then this is a, this is b, this is c3.
00:15
And we're told that the charge on c2, we'll call this q2, is three microculems.
00:22
So we want to know what's the, for part a, what's the charge on c1? well, the voltage should be the same across each of them because they're equivalent.
00:30
So we could write this as q1 over c1, which is the voltage on this, should be equal to q2 over c2.
00:39
And so then if we solve for q1, it's just going to be q2 times c1 over c2.
00:45
And we're told this is 6 microferds.
00:49
This is 3 microferats.
00:52
And then c3 is 5 microferds...
