Solving a Circuit Diagram with KVL & KCL

AI Thread Summary
The discussion revolves around solving a circuit diagram using Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL). The user presents their KVL and KCL equations but seeks validation and assistance in solving the circuit. There is confusion regarding the paths for current I6, with suggestions that it may be short-circuiting resistors R7 and R8. Participants indicate that R7 and R8 are not short-circuited but are in parallel with R3, and they recommend using Ohm's Law for simplification. The user is encouraged to clarify the circuit connections for better assistance.

Here is my circuit diagram.
http://s1227.photobucket.com/albums...n=view&current=untitled-1.jpg&t=1299237316875
I am unable to solve my circuit with the help of Kirchhoff's law:
Here is my KVL equations:
24-v1-v3-v8=0------(1)
v3-v2-v4-v7=0------(2)
v4-v5-v6=0------(3)
24-v1-v2-v5-v6=0------(outside loop i.e. 4)

And this is my KCL equations:
Is=I2+I3------(5)
I2=I4+I5------(6)
I5=I6------(7)
I4=I7------(8)
I8=I3+I7-------(9)
Is=I8+I6-------(10)



I have another thing to ask you experts that in circuits I have show two paths for I6 one is blue and other is red. I want to ask that form which way I6 will pass? either by blue or red??
My KCL equations are from the way i.e. blue.

Are my KCL & KVL equations are correct or not?
Kindly help me.

It looks like R7 and R8 are short-circuited across the bottom -- is that correct? That certainly would simplify the problem...

no no it is not short circuited.
it is connected with R3 and making a junction. I have corrected the mistake:

Now kindly tell me sir.
 
There is a lot of simplification available in this circuit.

R7 and R8 are in parallel and in series with R3.

R4 is in parallel with (R5 + R6).

You can probably just use Ohm's Law from there.
