We're looking for the equivalent capacitance of a set of capacitors.
00:09
And first we notice that this one and this one are in series.
00:19
So we can combine those first.
00:24
And to combine capacitors in series, there are 7 and 5 microferds.
00:32
To combine them in series, we can multiply them and then divide by the sum.
00:44
And that's about 2 .9 microferds.
00:50
So now we have something with three capacitors.
00:54
It looks like this.
01:04
And it doesn't look like we can combine these very easily.
01:09
So i'm going to try to redraw this in a way that makes a little more sense.
01:12
First of all, i can get rid of this wire because that's not really doing anything.
01:17
So then this becomes this is here.
01:21
Then this connection is right here...
