Find voltage for circuits with buffer amp

Click For Summary
SUMMARY

The discussion focuses on calculating voltage in circuits using buffer amplifiers and Thevenin equivalents. The participant successfully determined Vab as 10 volts through voltage division. They also identified the equivalent resistance of the first device as 16 ohms by combining resistances of 80 ohms and 20 ohms in parallel. The conversation emphasizes the importance of simplifying circuits by reducing devices to their Thevenin equivalents for easier analysis.

The Attempt at a Solution


I first found Vab which was 10 by using voltage division on the first device. By connecting CD to AB, the equivalent resistor is 80// 20, 16? I am not sure where to go from here.

Your life would be made easier if you first reduced Device #1 to its Thevenin equivalent and Device #2 to a single equivalent resistance. For part (2) draw the resulting circuit using your simplified device models.
