Hello students in this question we need to find out the capacitance between two points a and b we have the first capacitance c1 this is connected in this setup, right this setup and then we have an internal capacitance c3.
00:22
This is c2 and this is c2 and this is c3 it's further down connected to a setup of two capacitors so this if you look closely, these are all parallel so this is parallel again c2.
00:46
So we have to find out the effective capacitance so c1 is equal to 3 micro farad c2 is equal to 14 micro farad and c3 is equal to 1 micro farad so capacitors in general in series connection series capacitance will be equal to 1 by c1 plus 1 by c2 plus etc in parallel connections c1 c is equal to c1 plus c2 plus c3 etc.

This is all you need to know so now we can now connect all these things so we have two series here c1 and c1 so you get a total of 2 c1 so 2 c1 in parallel not 2 c1.
01:39
This is in series so you get 1 by c1 plus 1 by c1 that is equal to 2 by c1 so that is c1 by 2 is the effective c similarly this also gives you c2 by 2 and this is also parallel this is parallel so you can add it.
01:58
So that is this is 2 c2.
02:01
This is 2 c2 this is c2 by 2 and this is c1 by 2 right so c1 by 2 and c2 this these are both parallel so you'll get c1 by 2 plus c1 by 2 so that plus c2 by 2 is the total capacitance over here.

So this is in series with this setup...
