Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Do you know kirchoff's current law?
ya bus bohot long ho jaega
Any short method
Phle circuit ko redraw kr
Series parallel ki help se
Circuit ko single resistor m convvert krle fir v=ir se current nikal lena
Fir i ko distribute krdena current parallel m distribute hoga series walo m same rhega
Isse tujhe har resistance pr i mil jayega
Let me try
Current Law se long nahi hoga
Voltage (Loop) Law se, yes kaafi jyada
Lemme send my solution for reference abhi tum @Aman ka try karo
Is question m kvl kcl wale shi nhi rhega kyuki isme bhaut sari branch bnn rhi h
Ahhmm just realised
Ye
Mai actually saare questions kcl se hi karta hun
And I handle most of them in at most 3-4 lines
Koina bhai time k sath realise how jayega konsi chiz kha pr lgani h
Bhai Mera ho chuka hai 🙂
I was a 24 aspirant
Now I'm done with JEE NEET and all of that 😅
Although ye sab karna hi hai college me bhi but not majorly
The answer should be C
Is that correct? @Real potato
use thevenin
Yes that's a good approach but it's not really taught at many places
So I guess the generic equivalent circuit approach would suffice
It isn't much complicated of a circuit so doesn't matter
Whats this?
No its d
Huhh?
I think I've made some mistake
Lemme check
okay do send the soln if possible and whts this thevenin thing?
It's an approach to solve circuits like this one
I'll send a link here
Yes I'll send you a video link on that thevenin thing don't worry
Ok
Yes the answer is D
I'm sending the solution
Wait for a bit
One thing though
You're able to solve for the equivalent resistance right?
@Real potato
You get that it turns out to be 9 ohms eventually
Right?
Or should I explain that too?
Yes
So the total current is 1 Ampere
You agree on that?
Ye thevvenin theorem dekha mene but usme ye Vth nikalne ka kya fayda agar mujhe 4ohm ke across potential pata hi hota to me vese hi current nikal leta
Yes
I don't remember that right now honestly
Mai tumhe simple solution bhej raha hun just a bit
Oky
Check this out agar ye samajh aa gaya to aage bhi kar loge
I just assigned the negative terminal side to be zero
And the positive side become 9V because there's a battery of 9V
Then V=iR 'cause we know the current
Actually mene khud itna hi kr paya iske aage mujhe current ka distribution smjh ni aaya ki kese ho payega
8 ohms me 0.5 gaya?
To 2 ohms wali branch me bhi 0.5 gaya?
To uske aage same process lagayo
You'll realise current dobara half ho jayega
Apply kvl i would say...
Oky oky
Kvl would be lengthier here
Vaise ho gaya on paper ya bas samajh aaya abhi? 😅
it always is... 💀
But kcl is always better in my opinion
Like writing potentials makes things a lot easier
better would be to use kcl at the tri-junctions assuming potentiels....
I wrote the same lol
yup nodal analysis op 🔥 . i use nodal analysis myself like 99.84% of times.
But that would get messy in this case
my bad i might not have read ☠️
yup the easiest application of it would be in left most tri-node
I guess I do that every time
It was just this case that forced me to do some brainstorming
but sometimes it becomes paradoxical right?
in some cases.
Not paradoxical but messy to apply
Which makes us think we've written something incorrect because the law has failed
But it's our own oversight in most cases 😅
i used to think this.....but i do think nodal analysis doesnt work in some places...the reason ig would be that the voltage drop pattern isnt the same as we assume....it rarely happens man when i used to solve i used to encoutner....ill try to see a similar problem on this paradox if i find ill post it here!
abhi firse try kia ni bro subject switch krlia tha
I haven't any specific example
If you have one, then just drop a dm when possible
yup
series parallel se solve for req, ik it might sound weird and lengthy at first but the req is very easy to find here as it ends becoming the same branch again and again (you'll understand once you solve for req)
req se fir find current and then break it into branches
hardly 30-40secs me hojayega
if you don't have multiple batteries i feel looking for series parallel and symmetric circuits is the better option than kcl kvl
nodal analysis.......yes 🔥
idk what you generally mean by nodal analysis ;-;
its like identifying drop of potentiels across components, so like you can then see which nodes are under symmeteric potentiel drop pattern and club them....
@@Ameya²
acha got it
a basic method of solving, just didn't know the name :p
yeah its fine....name doesnt even matter as far as you know the process 😅
