Homework Statement
Find Voltage across a and b and the missing current (i)
so this is the circuit

Homework Equations
KCL and KVL
current towards the node is + away is -
Et = E1 + E2 + E3 in series
Et = E1 = E2 = E3 in parallel
Ohms law
E= IR
The Attempt at a Solution
KCL @ node c
3A-i1-i2= 0
i2=6V/3Ohms
i2=2A
3A-2A=i1
i1=1A
KCL @ node d
i2+1A-1A-i3=0
2A+1A-1A=i3
i3=2A
KCL @ node e
i3+i4-i
i4=24V/4Ohms
i4=6A
2A+6A=i
i=8A
KVL @ loop acdeba
E(ab)+i1(8)-6V-i3(12)+12V=0
E(ab)=-8V+6V+24V-12V
E(ab)=10V
so that's what i try..
my question is.. is those current direction is right?.. XD still don't know if i did it right..
so anyone who can help?
and the Voltage across AB.. am i right in having the loop acdeba.. neglecting the resitor which have 24V?
