Hi in the problem there is a combination of various capacitors.
00:08
First of all these two capacitors are in parallel i suppose this is stephen whose capacities has even as 6100 micro for it.
00:22
This is c2 having a capacitance of 2.00 micro farage.
00:28
Then two capacitors are in series with it, this is 8.00 micro ferret, suppose it is c3 and then one more capacitor in cities having the same capacity and see for is equal to eight 100 micro fabric and a battery providing nine walls to the circuit.
01:02
In the first part of the problem we have to find net capacities of this combination.
01:06
So first of all, as these two capacities semen and c2 are in parallel combination.
01:19
So their net capacity and c p will be given by 6.00 plus 2.00 micro farage.
01:30
Or we can citizens 8.00 micro ferret, no, this cpi and 8.00 micro farage and one more 8100 micro fabric capacitors are in series so equivalent the presidents of this combination will be given by one by cpp plus one by eight plus one by eight.
02:05
Here scp is also eight.
02:06
So this is one x 8 plus one by eight plus one by eight.
02:11
Or we can say this is three x 8.
02:15
So equi valent capacities of this combination is given us eight x 3 micro farid or we can say this is 2.67 micro carried.
02:28
Answer for the first part of this problem.
02:33
Now, in the second part of the problem we have to find charge at each capacitor out of these four capacitors.
02:41
So first of all we find net charge in the circuit for which we use expression musical to see these.
02:49
So for services equivalent capacities for me this is the battery potential.
02:54
So here it will be eight by three micro farid, multiplied by potential which is 9.0 wall.
03:02
So canceling this, we get it to be 24.0 my curriculum.
03:10
No, as you know, charge remains the same in series so as c4 and c three are in series.
03:18
So charge will remain same across these two as george remains the same in cities and c3 and c4 are in series.
03:43
So charge across them will be the same as the next charge.
03:46
So we can say q three is equal to q four is equal to 24 micro cooler...
