PROCEDURE:
Perform the steps indicated below for the circuit(s) of Figures 2 & 3.
Step 1. For the original circuit calculate the following:
a. The current through the load resistor (IL);
b. The voltage across the load resistor (VL);
c. I short circuit (ISC);
d. V open circuit (VOC). This is the Thevenin voltage (ETH);
e. The resistance (RTh)between the terminals A and B with the power supplies replaced by their internal resistances.
Step 2. Using the values obtained in Part 1 for ETH and RTH, draw the complete Thevenin equivalent circuits including all necessary details on the schematic.
Step 3. Construct the original circuits and measure the following:
a. All the resistor values being used.
b. The current through the load resistor (IL);
c. The voltage across the load resistor (VL);
d. The current through RLwhen RL = 0W (ISC);
e. The voltage from A to B with RLequal to infinity (VOC). This is the Thevenin voltage (VTH);
f. The resistance (RAB) between terminals A and B with RLremoved and the power supply replaced by its ideal internal resistance
Step 4. Construct the Thevenin equivalent circuit(s) using the values of ETH and RTH obtained from the above measurements and repeat all of the current and voltage measurements made for step 3a,b,c,d,e.
Step 5. Tabulate and calculate %error in the provided tables.
