Using Junction, loop rule to come up with 3x3 matrix, 3 equations-3 unkowns
Junction C:
I1 + I2 + I3 =0 (1)
Loop ABCF:
-[tex]\epsilon1[/tex] - I1r1 - I1r2 +I2r3 - [tex]\epsilon2[/tex]=0 (2)
Loop FCDE:
+[tex]\epsilon2[/tex] - I2r3 - I3r4 +I3r5 + [tex]\epsilon3[/tex]=0 (3)
I'm not so sure about r2 and r4 as to which current should I use.
