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.clearly no current flows through A3
so i can just apply kvl
like this
Is this wrong?
yepp
ans is 4.29
Ohh I'll try using kvl too
I'm getting 3.03
Nvm wrong prolly
Okay i got 4.28 using kvl
kaise
mera kahan galat hai
Haan dekhta hu
Shayad calc hi galat hai
Baaki sab shi lag rha hai
Oh man no
You changed polarity of 20V battery
ehhh
module se alag fig hai yaar yeh
wait ill send pi
c
8th
Damn
Ig you won't get 4.29 with this
Wapas calc karna hoga :')
🙂
Ye diag kahan se hai
online ques dhundha tha
taki photo na leni pade
but thats diff ques
Ooh kay I'll calculate and lyk
k
2.75
With module ka diag
So it's printing mistake prolly
class mei sabka match kaise kar rha tha fir bc
Hmm interesting
I'll need a pen paper for this dawg
Lemme see
How do you concur this
yeh fig dekhna
not the black one
Yeah lemme see
all the vertices are equipotential
for current to go through a3 there must be some potential drop since it has some resistance , unlike ideal ammeter with R=0
Haan wo to smjh gaya
Centre ka potential 8/3 aaya kya kvl se?
this is my working
mein direct current nikalta
Hmm lemme check
24/9
2.67 kyun aaya mera
Approximations liye honge maine
Simple kvl se nahi hojaaega?
Beech ka potential -10/3 aaega
Then just calculate currents
Haan wohi Kiya hai
Yes did that same val
-10/9 ya -10/3 idr kya tha
Yea
book mein 4.29 hai tho
Lemme check again
I guess 3rd branch mein current maan na hoga hume
Since resistance bohot Kam h
Nahi to answer nahi aaega
Weird question bro
I'm still siding with printing mistake in polarity of 20V batt
wrong it is then?
u still having doubt here?
Ek 2 logo se confirmation mil jati toh acha rehta
@Real potato can u take a look at this
Sure
Arey to bohot simple hai
@hardcoreisdead
ans confirm kardo pehle apna
yar ab calculate bhi karwaoge
:uhh:
ik the process
but idk why ans aint matching
..
my working
ruk jao calculator se karke bata ra ek min me
alr
4.29
Apx
116/27 kia
final ans??
Yup
meri working mei kya galti hai
ruko dekhra
Lag to theek raha hai
Kuch chota calculation error krdia hoga
mil hi nhi rha ðŸ˜
ek bar dobara starting se solve karlo aram se
Mil jayega error
Concept shi lagya hai
did twice already
Me likh k bheju solution?
sure
alright give me 5 mins
okk
and its not just me 2 other ppl have got same as mine
Sori for little kata peeti
ok i got same i2 as yours
can u find the error in my soln whilst i look at this soln
:Saul_Goodman: i can try
Mere solun me Kuch equations me error ho sakta hai plus minus ka cause im very sleepy mene calculator se ans nikal ke dia hai ngl
wait i got same i1 i2 but your aint 4.29
i1-i2 karna hai na
nahi shi hai eqns
Plus krega na bhai
Minus kyu
Mere diagram me dekho jo current battery se nikla hai i2
Wo ghum ke A2 wale branch se hi to ayega
Same goes for A1
A2 wale branch me or koi current nhi jayega
Islie plus
My 2nd attempt was same as yours but i2 opposite lia tha
By that logic i had to find i1+i2 , which is the current through middle 5 ohm resistor
,rotate
Ohhhh
I have to do
|i1| +| i2 |
Aagya ans?
Yes
Ammeter negative reading thodi dega
positive values ka sum
genius
I hve seen this que before lol
on the surface this is correct too
but
...
But
best not to jump on conclusions of i1+i2 in such cases
Obviously
Need to check na konse branch me kitna current jata hai
i directly deduced it to be the current in 5ohm resistor
I see
i1 i2 individually nikalna is the best option
thnx man
hafte bhar se doubt tha
+solved @Real potato
