(a) Formulate mesh-current equations for the circuit in Figure P \(3=20\).

(b) Formulate node-voltage equations for the circuit in Figure \(\mathrm{P}_{3}=\mathbf{2 0}\).
(c) Which set of equations would be easier to solve? Why?
(d) Use Multisim to find the node voltages \(v_{\mathrm{A}}\) and \(v_{\mathrm{B}}\) and the mesh currents \(i_{\mathrm{A}}, i_{\mathrm{B}}\), and \(i_{\mathrm{C}}\) in Figure \(\mathrm{P}_{3}=20\).
