Objectives: Applying Thevenin’s/Norton’s theorem to simplify circuits and measuring the values using the provided equipments. Proving superposition by disabling one source and calculating a voltage and then doing the same to the other sources and eventually adding the results to give the final value of the voltage to be measured. Finding the maximum way to transfer power to a load by modifying the resistances in the circuit and finding which resistances cause the circuit to deliver maximum power. Using different devices in some cases to measure the same voltage to be able to tell the accuracy differences between each device. 2
Results: 1) Thevenin’s equivalent circuit theorem: a b v = 2 V f = 1 kHz s rms + - R 1 R 2 R 3 v TH + - a b R TH a. Measured values of:   R1 = 10.48 Ohms, R2= 14.83 Ohms, R3 = 3.32 Ohms, Vs = 2.00 V(rms) b. Measured value : V(th) across (a-b): V(th) = 1.17 V c. Measured Value of R(th) = 9.477 KOhms.
