QUESTION 2.2
For the circuit shown in Fig. P2.1, select node d as the reference node, (a) Use nodal analysis to find the node voltages, (b) Use the node voltages to determine i1, i2, i3, and i4. Fig P2.1 For the circuit shown in Fig. P2.1, select node c as the reference node, (a) Use nodal analysis to find the node voltages, (b) Use the node voltages to determine i2, i3, and i4. For the circuit shown in Fig. P2.1, select node b as the reference node, (a) Use nodal analysis to find the node voltages, (b) Use the node voltages to determinei1, i2, i3, and i4.Explanation / Answer
There'll be four eqns.. four unknowns at node c, i2+i3+3=0 Vc=0 => (0-Va)/3 + (0-Vd)/4+3=0 (eqn1) at node b, i4=i1+3 (Vb-Vd)/2= (Va-Vb)/2+3 (2) at node a i1=i2+1 (Va-Vb)/2 = (0-Va)/3+1 at node d, i3+i4=1 (0-Vd)/4 + (Vb-Vd)/2=1 solve for Va,Vb,Vc,Vd and then you get i1, i2,i3,i4
