oh sorry that 10 should be 30 ,,
thx for the answer,, i got my Isc = 1.84 and Vth = 143.52
tried to use that mesh analysis
i got equations
60V - 90 Ia - 40V +30 Isc = 0
35V - 15V - Isc (5 +30 +45 +8) + 30 Ia +90 =0
then by elimination
igot Isc , correct me if I am wrong thanks

Find The Thevenins Equivalent of the circuit shown .
at the terminal a and b i think
Homework Equations
Vth = Rth(Ith)
V= IR
The Attempt at a Solution
For Vth
i tried using Nodal Analysis Having 4 Node Voltages
but i...
i double check the given here in my copy.. the circuit is right.. but not so sure about my computation :-p
so what do you think.. maybe the answer given by my prof is wrong? Vo = -50V :confused:
by referring to what you said sir,
i= (6v-0.004Vo)/ 2k
BY KCL
then 25(i)-Vo/40k - Vo/10k = 0
then substitute
25((6v-0.004Vo)/2l)) -Vo/40k -Vo/10k = 0
Therefore
Vo = 428.57V
Hmm :confused: still not the right answer ?

Find Vo
Vo = -50V (given answer by my prof)
Homework Equations
KVL
(Series) V=V1+V2
(Parallel) V=V1=V2
KCL
Current toward the node = Current Away from the node
V=IR
The Attempt at a Solution
i tried to solve for the i in...
the diagram is right.
the problem statement.. "Find the voltage across a and b" and find the current "i"
the 3A current source is placed like that.. there's nothing wrong with that
the blue line is the original diagram
and the current i1 , i2 , i3 and i4 is just my assumed direction..i...
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...
aw.. i forgot to put the value in E1 its 220V..
so itried using that Y-Delta Transformation,, then came to answer Rt= 15Ohms and the It= 14.67A..
so I am stuck again.. i don't know what should i use next to find i1.. should i use KCL by node
or should i use the KCL in series and parallel ?
