(a) Formulate mesh-current equations for the circuit in Figure P 3 -21 . Arrange the results in matrix form \(\mathbf{A x}=\mathbf{b}\).
(b) Use MATLAB and mesh-current analysis to solve for the mesh currents \(i_{\mathrm{A}}, i_{\mathrm{B}}, i_{\mathrm{C}}\), and \(i_{\mathrm{D}}\).
(c) Formulate node-voltage equations for the circuit in Figure P3-21 . Arrange the results in matrix form \(\mathbf{A x}=\mathbf{b}\).
(d) Use MATLAB and node-voltage analysis to solve for the mesh currents \(i_{\mathrm{A}}, i_{\mathrm{B}}, i_{\mathrm{C}}\), and \(i_{\mathrm{D}}\) and compare the effort required with each technique, that is, mesh-current versus node-voltage analysis.
(e) Use Multisim to verify your results in the previous two parts.
