Now we have two capacitors, and we have to find both capacidences, and there's just a little algebra that we have to do.
00:12
So we know that, let's say, c1 and c2, when they're combined in parallel, they have an equivalent capacitance of 9 picofarids, and combined in parallel means you can just add the 2 up.
00:29
So if i add the 2, i get 9, and when they're combined in series, they have an equivalent capacitance of 2 picofarids.
00:40
So to combine capacitors in series, we can say c1 times c2 over c1 plus c2, and that equals 2.
00:52
So now we just have a system of two equations.
00:56
And for the first one, i can solve for 1, which is 9 minus c2.
01:09
And now i can plug that in to this equation.
01:13
So 9 minus c2 times c2 over 9 minus c2 plus c2 equals 2...
