All have a capacitance of 1 micro farad. Find Ceq across AB.

Am not getting the equivalent circuit right :(


Will nip in at times to solve problems :)

3 C / 4

??

it is not important where u stand, but in which direction u are moving

see i have no means to draw the figure but let me try to ans these

i am adopting the following approach

let the capacitors be numbered so that from moving from left to right the numbering is

A, 1, 2, 3 , 4, 5 , 6 , B

on redrawing the circuit u get that 4 and 5 are short-circuited

equivalent circuit is that 1,2 and 3 are in parallel and are in series with 6th capacitor

then

equivalent capacitance = 3C/4



RATE ME

all the best ...

Let the pot of A be V1  and the pot of B be V4  ( if we go on naming 1, 2 etc we reach 4).

3 capacitors have P.D  V1 - V2 . So they r in || and eq is 3C

2 capacitors have P.D  V2 - V3 . So they r in || and eq is2C

1 capacitor  have P.D  V3 - V4 .

As we hav to find the eq cap btw A and B , across which the PD is V1 -V4 , the 2 cap of eq  cap (  2C ) is out of circuit.

So 3C and 1C is in series and result is  3C / 4.

Finally we put C = 1 micro F

it is not important where u stand, but in which direction u are moving

The diagram wil be A goes to 3C ( pd V1 - V2 )  and 2C ( pd V2 -V3 )  in series and frm a point between them comes out 1C  ( pd V2 - V 4 ) which ends in B.

it is not important where u stand, but in which direction u are moving

circuit diagram by elasti is right

that is what i meant in my explanation

all the best ...
