    ri R$ 7:) Here, each V represents a change in voltage (in volts) at a battery, each R represents a resistance (in ohms) at a resistor and each I represents a current (in amps) through a wire. These quantities obey two simple laws: 1. Ohm's law: The voltage drop across a resistor is V = IR. 2. Kirchhoff's second law: The sum of all the voltage changes in a closed loop is zero. Using these two laws, we can construct...

    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...
