Network Measurement Laboratory - Lab Report ExampleThis try is aimed to experimentally determine the Thevenin and Norton equivalent circuit of a Black box mesh topology which consists of resistive elements and voltage source. Furthermore, the value of the load resistance connected crossways the two conclusions of the black box will be determined such that maximum power is transferred from the network load. Finally, the objective of the experiment is to determine certain network parameters. This experiment will aid the students to understand the behavior of given circuits and explain their outputs, understand Thevenin and Norton principles, the principle of maximum power transfer and their implications for practical systems.Thevenin Theorem states that any bilinear terminal circuit is equivalent to an ideal voltage source Vth in series with a resistance Rth where Vth is open circuit voltage the two terminals and Rth is the proportionality of open-circuit voltage to the short-cir cuit current (Isc) at the terminals. On the other hand, an alternative proposition to Thevenins theory, Nortons theorem states that Any linear resistive two terminal circuit is equivalent to a parallel combination of an ideal current source In and a resistance Rn, where In is the short-circuit current at the terminals and Rn is the ratio of the open-circuit voltage to the short-circuit current. These theorems are illustrated in the circuit belowMeasurements for the values of 12 VDC and 18 VDC of the excitation voltages were then made. The Thvenin Circuit Component was then turned over and a schematic diagram representation drawn as shown belowA 10K variable opposition was connected across the output of the black box and the current and the voltage across the resistor measured. The resistance was varied the current and voltage recorded as a function of the resistance. The current and the voltmeter measurement
