2.10a

\frac{V_o-0}{1000}+.002=0 \Longrightarrow V_o=-2

2.10b

\frac{V_o-5}{3000}+.002=0 \Longrightarrow V_o=-1

2.10c

\frac{V_o-0}{15000}=0 \Longrightarrow V_o=0

2.10d

V_o+2-5=0 \Longrightarrow V_o=3

2.22

Nodal equation at V_+

  • \frac{V_A-V_+}{R_A}+\frac{V_B-V_+}{R_B}=0 \Longrightarrow V_+=\frac{V_AR_B+V_BR_A}{R_B+R_A}

Nodal equation at V_-

  • \frac{V_o-V_-}{R_2}+\frac{0-V_-}{R_1}=0 \Longrightarrow V_o=\frac{(V_AR_B+V_BR_A)(R_1+R_2)}{(R_B+R_A)R_1}
