IV. PROCEDURE:
1. Connect the circuit shown in Figure 8.3
2. Measure and record the current I in the 10 ohm resistor.
3. Disconnect the 10 ohm resistor.
4. Measure and record Eo, the voltage across terminals a and b.
5. Disconnect the voltage source EA and place a short-circuit across
the network between A and A'.
6. Using the VOM, measure the resistance Ro between a and b.
7. Compute I' = Eo / (Ro + RL) where RL = 10 ohms. Compute for
the percent difference between I and I'. Record these values.
8. Repeat steps 2 to 7 using the circuit shown in Figure 8.4.
