Matlab question: Resistive networks are well-represented by linear equations. Consider the DC circuit shown below: Figure 1 This problem can be converted into a system of simultaneous linear equations by applying Kirchhoff's law and Ohm's law. In circuit design, i represents current (measured in amperes, A), V represents voltage (in volts, V), and R represents resistance (in ohms, ohm). Kirchhoff's law states that the sum of the currents entering a node is equal to the sum of the currents leaving...
