Solution :
current in R4 and R3 is (6-5)/5=1/5A
VCD=VCA=VCB (no current is flowing through R1)
V=VCB=E2+iR2=2 + 2/5=12/5A
E=(1/2)CV2

OH KK.....
THANX YAAR......... thanx a ton!!!
BTW ek doubt tha.......
Y didnt u make use of R3 in ur calculation?
Was it bcoz it didnt fall in the LOOP that u had selected?
Does that mean No matter wat be the value of R3 our answer does not change?? [7]
bahut bekar bane hain i know agar kuch samajh na aaye to puch leena
nahi step 1 main R3 use hoga find net current 5 and 4 ohms in parallel so net resistance 20/9 hoga net i=27/10 current in req branch dat is 2 ohm and 3 ohm wala branch will be 6/5 A
thn how did u get 6/5A buddy,
coz E = E1 = 6V;
Thn how did u gt R =5??
in step 1 we will certainly use R3 but in next 2 steps u replace R1 by a wire with 0 resistance so whole of current will pass through it and R3 will be useless thats why i didnt use it in step 2 and 3

answer nahiin match hora kya? tera method toh sahiin hain. use the fact that it offers infinite resistance in steady state
k we use superposition principle
another thing we hav to find V btw E2 and end of R2
ie ---------||-----------/\/\/\/\----------- ----------------> (arrow shows the direction of current)
||=E2 /\//\/\/\=R2
now step 1:
replace E2 and E3 by wires and find the current in above part of circuit shown with only E1
we will get a current 6/5 A parallel to the given directional arrow ( which i showed above)
step 2
similarly replace E1 and E2 and calculate current in req part of circuit
it comes out to be 2/5 A opposite to the arrow i showed
similarly step 3
using only E3 we get 3/5 A in opp dir to ma arrow
so net current in our required part of circuit is 1/5A parallel to ma arrow
now find the required potential drop V=12/5 V
so energy = 5*12*12/2*5*5=144/10=14.4 units

YAH VISH
u r crrct bro! ans givn is C
Can u pl. post ur workin in a lil mor detailed way
i did it by superposition and of coure R3 has to be considered for it
lagta aisa hi he.... the symbol is lil wierd but I m not sure if its ohm or sumthing else..... par in da diag resistor only has bn shon
pl. try this yaaron...........
Its quite simple, u jus need to assert or oppose the solution provided........
MY MAIN DBT. IS : Y DONT V CONSIDER R3 wile calculatin resistance?
NO.
ACTUALLY, my methd dusnt match wid da abov mentioned methd..............
its a que frm Tiit FT1
but y do v not consider R3?????????????/
