Find $I_o$ in the network shown using linearity and the assumption that $I_o = 1 mA$ given that $I_s = 3 mA,$ $R_1 = 6 k\Omega , R_2 = 2 k\Omega, R_3 = 8 k\Omega, R_4 = 10 k\Omega$ and $R_5 = 6 k\Omega.$

If $I_o = 1 mA$, then calculate the following values:
$V_2 =$ $V$
$I_3 =$ $mA$
$I_2 =$ $mA$
$I_1 =$ $mA$
$I_S =$ $mA$

Using linearity with an actual value of $I_s = 3 mA$,
$I_o =$ $mA$
