i dont understand how c2 and c3 are in series but are parallel to c1

Ok, so, what defines parallel and series is if whether the potential difference across or the current through the components is the same

Not kidding A friend of mine is asking me “exactly” the same question rn In my dms
Sephrina
SephrinaOP3mo ago
can we like 😭
Varun_Arora
Varun_Arora3mo ago
Trying to explain to him
Sephrina
SephrinaOP3mo ago
this is og question i think
Opt
Opt3mo ago
Now, the current (charge) through the capacitors is not necessarily the same, because there are other pathways for the charge to flow, and not just in a straight line through the capacitors
Varun_Arora
Varun_Arora3mo ago
Maybe @Opt ka view point dekh ke use better samjha paaun
Opt
Opt3mo ago
However, if we consider points connected by straight wires(ideal conductors), they must be equipotential, since charge will flow until the two points become equipotential.

SephrinaOP3mo ago
i dont understand this heavy language 😭
Opt
Opt3mo ago
Ok ok, I'll explain in simple terms
Sephrina
SephrinaOP3mo ago
thnks
Opt
Opt3mo ago
Because there's a straight wire from A to another point (I'll call it point 2), both the points are at the same potential Got that? Same logic applies to the straight wire from B to Point 1
Sephrina
SephrinaOP3mo ago
wait wait like in between which capacitor because 2 a are there
Opt
Opt3mo ago
I can't draw rn so I'll write. A C1 P1 C2 P2 C3 B Is the diagram A and P2 are connected by wire B and P1 are connected by wire So, A and P1 are made equipotential B and P2 are made equipotential
Varun_Arora
Varun_Arora3mo ago
Uh uhh
Sephrina
SephrinaOP3mo ago
ok i kinda get it
Opt
Opt3mo ago
So, that essentially means that we can call P2 A, and P1 B. That's the thing that they've done here Which weirds people out unless you're writing it on a board And showing what you're changing
Sephrina
SephrinaOP3mo ago
so before the c1 the potenital is same as between c2 and c3 right? exactly
Varun_Arora
Varun_Arora3mo ago
Now, I’m not getting this which I apparently was a few moments ago
Opt
Opt3mo ago
Yeah the potential across each capacitor is V(A)-V(B) Sorry 🙇
Varun_Arora
Varun_Arora3mo ago
Will try coming up with something Nahi to will dm you if that’s okay
Sephrina
SephrinaOP3mo ago
half got it half not
Opt
Opt3mo ago
Ok, seph ji, one last thing You got the equipotential thing right?
Sephrina
SephrinaOP3mo ago
ys two surfaces which have same potential in this case the points named a have same and same on b
Opt
Opt3mo ago
So, C1 is connected between A and P1, but P1 is equivalent to B, so why not just connect it to B instead? C3 is connected between P2 and B, but P2 is equipotential to A, so just connect it to A instead of P2 C2 is connected between P1 and P2, but those are the same as B and A, so just connect it between B and A What do you end up with? Three capacitors connected in parallel between A and B

SephrinaOP3mo ago
yh i got this yh but hre it says in book that c2 nd c3 are in series
Varun_Arora
Varun_Arora3mo ago
One question How do you explain that “physically”? Solving it is one thing, we have this workaround
Opt
Opt3mo ago
The logic is, "All we care about is potential. So if two points have the same potential, then changing connection of a component from one to the other makes no difference."
Sephrina
SephrinaOP3mo ago
dont confuse me more
Opt
Opt3mo ago
No they aren't.
Varun_Arora
Varun_Arora3mo ago
Yeah it doesn’t that’s fine The circuits are equivalent But how does the circuit physically work when the connections are not changed
Sephrina
SephrinaOP3mo ago
book has it wait i will send thier explanation

@Opt you got something on this?
Opt
Opt3mo ago
Uhhh yeah, but it's tedious to type It's just charge induction A lot of it
Varun_Arora
Varun_Arora3mo ago
Trying to visualise it but really weird
Opt
Opt3mo ago
Yeah
Varun_Arora
Varun_Arora3mo ago
Was trying to figure out the same in the case of resistors
Opt
Opt3mo ago
Because the wires in the middle make it so that charges can flow out of the system too
Varun_Arora
Varun_Arora3mo ago
I ain’t thinking in terms of capacitors for ‘cause that’d be the same
Opt
Opt3mo ago
Then it's just Ohm's law
Sephrina
SephrinaOP3mo ago
what
Varun_Arora
Varun_Arora3mo ago
I mean how do you physically make the current go through a wire where there is no potential difference
Opt
Opt3mo ago
That's the neat part, you don't.
Varun_Arora
Varun_Arora3mo ago
So youre saying It goes “straight”?
Sephrina

kisi ko pta hai kya 😭??

can u like do it later and send it later?
Varun_Arora
Varun_Arora3mo ago
How do you go from Vb to Va then
Opt
Opt3mo ago
Ah, ok, see no.
Varun_Arora
Varun_Arora3mo ago
That one’s easy I’ll do it in a bit wait
Opt
Opt3mo ago
You can imagine that higher voltage means a greater collection of charges. So there's clusters of charge at points at VA
Varun_Arora
Varun_Arora3mo ago
Alright Then How do they exactly move?
Opt
Opt3mo ago
And charges will try to flow to a less dense cluster Which is VB For the leftmost cluster, it has to go right
Varun_Arora
Varun_Arora3mo ago
Yeah For the middle one
Opt
Opt3mo ago
For the cluster in the middle, it can flow left, or flow right So it does Once it flows left, it can, without any resistance just go to the rightmost point So it will do that instead of taking a path with a resistance

You checked something about the cyanide?
Opt

Oh crap no. Lemme go do that. My clayden pdf needs to be redownloaded
Varun_Arora
Varun_Arora3mo ago
I digged and now I’m questioning the pka or water Dug* Clayden won’t give you much I guess I checked it Maybe I’m wrong too so do check it out as well
Opt
Opt3mo ago
Nvm that has hard and soft nucleophiles, not acid-bases
Varun_Arora

Yeah We could get some idea seeing how it explains cyanide reactivity though

what to explain in this, why they are in series?
Sephrina
SephrinaOP3mo ago
i have same question
Prasan
Prasan3mo ago
They arent in series All of them are in parallel
SchrodingerBilla
aren't these all are in parallel?
Sephrina
SephrinaOP3mo ago
my book says otherwise
SchrodingerBilla
you are seeing answer of fig 4 you asked fig 3
