Capacitence
2 capacitors are unknown are connected first in series then in parallel with 100V battery. If the energy stored in combinations is 0.045J and 0.25J respectively. find the vale of capacitence of capacitor

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.i was good to get till the relation of series and parallel equivalent
but after that i am getting a weird quadratic which is not giving the right answer
1/2 * C_series * V^2 = 0.045
1/2 * C_parallel * V^2 = 0.25
where V is 100V
yahi kiya kya?
one of my friend used the ratio method but im not quite able to use tht
yep
basically it used math identity and im dumb in there
this was my till tht part
where im correct
but after that this khichdi
@WOLVERINE ye karo na
1/2 cv squared se ni ho rha?
lemme try
vaha se aarha but mera nhi aara
matlab ki vo karne ke baad ratio kar rhe hai to usme nhi hora merese
wait i might just get the ans
im halfway
dekho, aise lambe route se bohot time lgega krne mein, do what i do for quick solving, just analyze the options, agar options series aur parallel ko satisfy kr rhe hai toh woh sahi hai warna nhi
work smart, not hard
subjective hai que
good technique but its better you get the answer properly
objective to kya hi baat thi
for this exact reason
arey NEET mein thodi na subjective hoga
lol
neet hai bhai
are ik but ques to que hai
time management is the key
yeah got it
but just keep that in the back of your mind
as a thing you can do
dont forget it
sridharacharya formula lgta hai isme
š
( i use that coz quadratic eqn tough bante hai yahan)
ye konsa naam hai
hnnn
im getting the value of one capacitence correct
other is wrong smh
arey won ganda wala formula padha hoga naa 10th mein
c1 is coming wrong
bhai minus krlo naa š
usi se glt ara
?
calculation error lag rhi hai lmao
5-C2
definitely calc error
if you got one
just sub it into whatever linear equations you have
you get the second
check yo calcs
x = (-b Ā± ā(b2 - 4ac)) / 2a
ik for sure its calc error but ive tried like 3 times im not getting it
yeh wala
quadratic formula
i made this just today for bitsat, might be helpful
by mental loop i mean that sorta thing
knowing you're doing it right but getting it wrong again and again
ive dne the first two
skull
vaapis aa jana baad mein
nhi abhi karke rahungi
ok :sweaty:
idhar pe C1 aa nhi ara
C2 sahi hai
C1 should be 0.4 * 10^-4
im gettin 0.53 *10^-4
im going to try again
bhai, c1+c2 calculate kiya naa pehle š
usi mein se minus krlo c2
c1 aajayega
usi se minus kiya hai
root shyd glt hai
bhai (50x10^-6) - (10^-5)= 40x10^-6
š
simple math
aree c1 -c2 ki value 14 * 10^-6 ay hai
hein
hein kya vahi to bolri
arey yaar c1+c2=(5x10^-5) aur agar c2 nikal liya toh c1+c2 ki jo value hai usme se c2 minus krogi toh apne aap c1 aajayega naa š
c1-c2 kyu krna š
vo mai smj gyi par c1 c2 se aaya hai
meri soln me
last mein calculation error hoga
check kro
anyways, imma go now
