DISCUSSION: The series-parallel circuit shown in Figure #1 is to be analyzed using Thevenin’s Theorem. During this experiment you will measure Thevenin’s equivalent circuit and subsequently verify your results using Pspice. Thevenin’s equivalent voltage directly measured as the open-circuit voltage with the load capacitor, CL removed. Thevenin’s equivalent impedance will be calculated by first measuring the following parameters; vOC (open-circuit voltage) and iSC (short-circuit current) and then satisfying the equation given below: ZTH = vOC / iSC 1 ELEC195 LAB #8 2/6/03 J. F. Santacroce SCHEMATIC: Figure #1 REQUIRED EQUATIONS: ZTH = vOC / iSC Z1 = R1 + jXC1 Z2 = R2 + jXC2 Z3 = R3 ZL = CL PROCEDURE: 1. Construct the circuit shown in Figure #1. Set the HP-33120A Function Generator to a 5VRMS (sine wave) with the frequency at 16kHZ. Measure the required circuit parameters, in polar form, as required in the following table. e = _________________ (polar form) vL = _________________ (polar form) iL = _________________ (polar form) VOC = _______________ (polar form) iSC = _________________ (polar form) 2. Construct Thevenin’s Equivalent circuit using both the Decade Resistor Box and the Decade Capacitor Box and measure: vL = _________________ (polar form) iL = _________________ (polar form) 2
