Hello,
I'm looking to work out the current at I in the following circuit using Kirchoff's current law and nodal analysis:
[PLAIN]http://img853.imageshack.us/img853/4792/circuitgem.jpg
Using Kirchoff's voltage law (and loop analysis), I got a current of (35/22)A, but for the current law method I'm having problems.
I obtained the following equations using Kirchoff's current law:
4i1+2i2+4i3=5
-4i3-2i4=-10
and nodal analysis:
-i2+i3-i4=0
i1+i4=I
But solving these 4 equations produces a value for I of 0, which doesn't make sense, let alone agree with the answer using the other method.
Any help will be greatly appreciated.
Thank you
