Laboratory Period #3: Network Theorems Alexander Hyatt March 6 th , 2008 ECE 309 – 012 TA: Trey Shirley Abstract: The purpose of lab 3 is to study certain important network theorems, which are used frequently in circuit analysis, and to improve skills in applying these to practical circuits. Experimental and analytical methods are compared. The results from the lab confirmed the theories as being practical and existent in the real world.

Apparatus or Equipment: o DC power supply o Decade Resistance boxes (2) o Digital multimeter o Function generator o Digital Voltmeter o Digital Ammeter o Voltage Source Procedure: Thevenin’s Theorem, dc circuit Figure 1: Circuit setup 1 from ECE 309 Lab Manual 1. Construct the circuit shown. Measure the voltage across A-B, this is the Thevenin voltage, V T . 2. Measure the short-circuit current, I SC , by connecting A to B through an ammeter, you are using the ammeter’s very low resistance to short A to B. Use a scale greater than 2mA. 3. Compute the Thevenin resistance, RT, by: RT = V T / I SC . 4. Construct the Thevenin equivalent circuit from this data, and compare it with the original circuit.
Thevenin’s Theorem, ac circuit
