No I mean what is the condition?

- anonymous

How can you just look at it and say for sure that hey this is series/parallel

usually we don't get capacitors of desired value ...

- anonymous

Yeah so we couple them to get capacitors of desired value.But while looking at huge circuits I am having problems figuring out which is series or which is parallel

- anonymous

You need to practice, only then you can make out the circuits properly.

- anonymous

So basically there is no definite rule?

- anonymous

There is, but to get better sense you need to practice.

- experimentX

capacitors behave differently for ac and dc ... seriously i hate capacitors.

- anonymous

So how do I identify one then

- anonymous

Post one of your circuits. I will see if I can help you.

- anonymous

Just a sec Ill see my book

Or, parallel network

Need to find capacitance

I got the first part.Need help in the second junction

- anonymous

You will need to take q(charge) instead of current. And then apply kirchoff's law in the loop.

wow .. Ishaan looks like a real professional.

- anonymous

|dw:1333491397042:dw| In this part which is series or parallel?How

- anonymous

\[\frac QC = V\]
Q is for charge, C for Capacitance and V for electric potential. I think you must know about it.

- anonymous

Yeah I do

- anonymous

Look at the experimentx's diagram he explained it.

- anonymous

Didnt get it fully.Just need to know which is series and which is parallel

- experimentX

let's begin at the here |dw:1333491659145:dw|

- anonymous

Ok got that then?

- experimentX

it has an equivalent of half micro farad

- anonymous

No it's 2

- experimentX

i think it's half ... for series.

- experimentX

let's ask ishaan

- anonymous

1/c=1/c1+1/c2

- anonymous

1/c=1/4+1/4=1/2 means c=2 right?

- experimentX

those two at series, would certainly make half micro farad

- anonymous

But why?According to the formula it must be 2

- anonymous

Each one is 4

- experimentX

Oo .. i thought it was each capacitor was 1 micro farad

Ok got it thanx guys.

|dw:1333492123125:dw|

- anonymous

Total is 8microfarad

- experimentX

oo,, yes ... 2 + 6

- anonymous

Is it 1+1/2+1/4.......

- anonymous

Yes, or just 2

- anonymous

Yeah

- experimentX

i think 1+1/2+1/3+ .... diverges..

- anonymous

How does it go by 1/3

- anonymous

I think it's 4 not 3 experimentx

- anonymous

musn't the next one be 1/4?

- experimentX

oo ,,, didn't see the picture clearly. you are right.

- anonymous

That's all I think.Ill practice more to get the touch of it
