why is option third wrong? i got ans as 0.16 and it is rounded off to 0.2

1/6 is what i got

[red leaf]

There's no closed circuit at all....there won't be any current flow right?

[waxen fern]

S 2 is closed

[red leaf]

Yeah still

Circuit is broken at fully filled capacitors

[waxen fern]

yes but the potentials across the C2 30 ohm and 10V should be same as the potential across C1 and 70ohm right

[red leaf]

Ah right

[runic shadow]

wdym both circuits are closed

[runic shadow]

5/30

1/6

shouldnt it be the ans

since all capacitor will be in steady state

[waxen fern]

What how

[waxen fern]

After the switch is closed the charged capacitors will behave like batteries and the uncharged one becomes short circuited

[runic shadow]

only 1 capacitor not in steady state

we will only take 30 ohm in to acc no?

[runic shadow]

what

look

first S1 is closed for long time so all C in steady state

wait a sec

nvm idk

[runic shadow]

what why?

[waxen fern]

Potential diff across the same points is the same

Same logic used in parallel circuits

[runic shadow]

oh u taking them as a whole ic

[runic shadow]

where did 130 and 4 come from in right most wire

[waxen fern]

100 and 30 are in series and then the capacitors were giving emf in the opposite direction of the battery so 5-0.5-0.5

[runic shadow]

ah ic

still

wont they be in steady state so no current passes through?

if u say they will discharge , can they even discharge when battery there?

[waxen fern]

When you close the switch S1 why is the current flowing werent they in steady state before.When the system changes the steady state will be disturbed and it will want to go towards another steady state

[waxen fern]

Yes
