Applying KCL at node A.

\(\frac{{V + {V_2}}}{5} + \frac{{V - 10}}{2} + \frac{V}{8} = 0 \)

\({V_2} = 3\;{V_m} = 3\frac{{\left( {V - 10} \right)}}{2} \times 2 \)

V2 = 3V – 30

\(\frac{{4V - 30}}{5} + \frac{{V - 10}}{2} + \frac{V}{8}= 0\)

32 V – 240 + 20 V – 200 + 5 V = 0

57 V = 440

\(V = \frac{{440}}{{57}}\)

\({\left. I \right|_{{R_3}}} = \frac{V}{8} = \frac{440}{57\times 8}=0.96~A\)
