By inspection, find the node voltage equations for the circuit given by the diagonal and off diagonal conductive terms are g11 equals 1 plus 5 which is equals to 9 s.
00:24
G22 is 1 plus 2 which is equals to 3 s.
00:29
G3 equals 2 plus 2 which is 7 s.
00:36
Now for the off -tagonal terms, g12 is minus 1, g13 minus 5, g21, g21 minus 1, g231, g2 31 is minus 2, g31 is minus 5 and the last term, g32 is minus 2.
00:59
And the current terms are i1 equals 4, i2 equals 2 and i3 is 1.
