1. The problem statement, all variables and given/known data Find Voltage across a and b and the missing current (i) so this is the circuit http://img3.imageshack.us/img3/184/circuitsf.jpg [Broken] 2. Relevant 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 3. 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 thats what i try.. my question is.. is those current direction is right?.. XD still dont 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?
