Question no. 140..

Answer 1

it may be answer 4C in first two circuit connected in series than when find the equivalent resistance then it will connected in series with another circuit
in first 2 circuit were found then next two circuit are connected in series and one circuit didn't connect with any other circuit

Answer 2

let's spotify circuit

Hey there

See in my diagram

Here in 1 st and 2 nd capacitor

As each plates are already connected

also A is connected to c

So 1 and 2 is in parallel

Therefore equivalent 2c

Now 3rd plate and 2c in parallel because B and D are connected

So 3c equivalent

Now see 4 and 5

Its in parallel because D and E are connected

So now 3c, 2c( 4 and 5 th equivalent )and 6 th one becomes in series

So

Net capacitance

1/Ceq = 1/3c + 1/2c + 1/c

= 2 + 3 + 6)/ 6c

= 11/6c

Ceq = 6c/11
