    Question : Thevenins Equivalent

    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

    Finding Vo in a two-loop circuit using KVL and KCL

    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:

    Finding Vo in a two-loop circuit using KVL and KCL

    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 ?

    Finding voltage across nodes and missing current with KCL and KVL

    am i right that in ur analysis u also neglect the presence of the 24V at current i4

    Finding voltage across nodes and missing current with KCL and KVL

    ahm can you please show ur computation in doing it separately.. i might have another idea in solving future circuit problems... thx

    Finding voltage across nodes and missing current with KCL and KVL

    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...

    Finding current and power in series-parallel resistor circuit

    so i got this answers. i1= 2.44A i3= 7.304A then my P= 533.48 is this right?

    Finding current and power in series-parallel resistor circuit

    At node B i2+i3+i1=0 at node C i3+Io=i4 now tryring what you said, ill inform you of my answer and correct me if I am wrong.

    Finding current and power in series-parallel resistor circuit

    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 ?
