After re-drawing the circuit, we get

F1 J.P 18.5.20 Pallavi D2

By applying KCL at node ‘A’, we get

\(\frac{{1 - {V_A}}}{{1k}} = \frac{{{V_A}}}{{1k}} \Rightarrow {V_A} = \frac{1}{2}\;Volt\)

Now applying KCL at node ‘B’, we get

\(\frac{{1 - V - B\;}}{{1k}} = \frac{{{V_B} - {V_0}}}{{2k}}\)

2 – 2 VB = VB = V0

Where, VB = VA = 0.5 volt (∵ virtual ground)

∴ 2 – 1 = 0.5 – V0

V0 = -0.5 Volt
