1 Experiment 2: Analysis and Measurement of Resistive Circuit Parameters Report Due Inclass on Wed., Mar. 28, 2018 Prelab must be completed prior to lab. 1.0 PURPOSE To (i) verify Kirchhoff's laws experimentally; ii) investigate the concept of power absorption and power delivery; and iii) demonstrate experimentally the principle of superposition in circuit analysis. 2.0 INTRODUCTION Certain network principles and theorems can be used to considerably simplify the analysis of complex circuits. Circuits with multiple independent sources can often be analyzed by considering the effects of the independent sources one at a time. In the design of circuits, the principle of superposition allows the desired response of a complex circuit to be expressed as the sum of the responses due to each independent source. This approach allows the designer to reduce the design of the complex circuit to the design of simple circuits. It is important to note that, for circuits with multiple independent sources, some power sources may absorb power while other sources may deliver power. Once a complex multisource circuit is divided into multiple simple circuits where each circuit has a single power source, basic circuit analysis approaches can be applied to evaluate all voltages and current associated with each element in the circuit. In addition, Ohm's Law, Kirchhoff s current law and Kirchhoff s voltage law are simple but sufficient laws that form the basis for electric circuit analysis and synthesis. Kirchhoff s laws apply to the interconnection of elements rather than to individual elements. The laws describe the inherent constraints on voltage and current variables by virtue of interconnections. Essentially, these laws follow from the conservation of energy and continuity of current (or conservation of charge) principle. 2.1 The Electric Circuit An electric circuit consists of circuit elements, such as energy sources and resistors, connected by electrical conductors or leads to form a closed path or combination of paths through which current can flow. A point at which two or more elements have a common connection is called a NODE. A twoterminal circuit element connected between two nodes is called a BRANCH. A branch may 1
2 contain more than one element between the same nodes. When two or more circuit elements are connected together an ELECTRIC NETWORK is formed. If the network contains at least one closed path, the network is called an ELECTRIC CIRCUIT. 2.2 Kirchhoff's Laws Kirchhoff's Current Law (KCL) Kirchhoff's current law describes current relations at any node in a network. It states that the algebraic sum of the currents at any node is zero. Kirchhoff's current law relates to the conservation of charge since a node cannot store, destroy or generate charge. It follows that the charge flowing out of a node exactly equals the charge flowing into the node. An equivalent way of saying this is to say that the current at a node is continuous Kirchhoff's Voltage Law (KVL) Kirchhoff's voltage law describes voltage relations in any closed path in a network. It states that the algebraic sum of the voltages around any closed path is zero. Kirchhoff's voltage law expresses the principle of conservation of energy in terms of the voltages around a closed path. Thus, the energy lost by a charge travelling around a closed path is equal to the energy gain. 2.3 Principle of Superposition The principle of superposition states that the response (a desired current or voltage) at any point in a linear circuit having more than one independent source can be obtained as the algebraic sum of the responses caused by each independent source acting alone, i.e., with all other independent sources set to zero. An independent voltage source is set to zero by replacing it with a short circuit, and an independent current source is set to zero by replacing it with an open circuit. Note that the principle of superposition is a consequence of linearity and hence applicable only to linear circuits. Superposition allows us to analyze linear circuits with more than one independent source by analyzing separately singlesource circuits. 2.4 Power Calculation The power associated with a basic circuit element is given by p = vi (1) where p is the power in watts, v is the voltage in volts, and i is the current in amperes. 2
3 Resistors always absorb energy and dissipate power. Power sources, on the other hand, can either deliver or absorb power. From our circuit analysis, we should be able to determine whether power is being delivered to a given electrical element or extracted from it. We can use passive sign convention to achieve this objective as follows: 1. If the reference direction for the current is in the direction of the voltage drop across the terminals of the element as shown in Figure 1, + v i 1 2 v + i 1 2 Figure 1 then p!"# = vi (2) 2. If the reference direction for the current is in the direction of the voltage rise across the terminals of the element as shown in Figure 2 i i then + v 1 2 Figure 2 p!"# = vi (3) To summarize, when positive charges move through a drop in voltage, they lose energy, and as they move through a rise in voltage, they gain energy. v References [1] J.W.

Note that the resistance of each resistor must be measured separately. Also, record the standard values Construct the circuit of Figure 3 on the breadboard provided. Do not connect the voltage sources to the circuit (that is, leave ac and bc as open). Set the DMM to read RESISTANCE Place a short circuit between nodes b and c, and connect the DMM to nodes a and c to measure the equivalent resistance of the resistive circuit as seen by voltage source v!!. Record the value as the measured R!"! in Table Remove the short circuit between nodes b and c. Place a short circuit between nodes a and c.

Record this as v!! in column 2 of Table 2. Note: It may not be possible to adjust the source to read exactly +10 V; simply record the closest value that you are able to obtain Turn off the power (voltage source) on the breadboard. Connect the breadboard voltage source to the resistive circuit at points a (red lead) and c (black lead). DO NOT POWER ON the voltage source Place two AA batteries inside the battery holder. DO NOT SHORT CIRCUIT the two terminals of the battery holder. With the DMM set on dc volts, measure and record the total voltage of the battery pack.
