Engineering KVL and sensitivity of a simple circuit

Click For Summary
The discussion revolves around applying Kirchhoff's Voltage Law (KVL) to a simple circuit and understanding its sensitivity. Participants express uncertainty regarding the application of KVL and seek clarity on the equations involved. A reference to a diode concept is provided for additional context. There is also a suggestion to rotate the schematic by 90 degrees to aid in understanding the sensitivity aspect. Overall, the conversation focuses on resolving confusion surrounding KVL and its implications in circuit analysis.

For the last sensitivity part, equations be falling out of the sky...

See if it helps with the schematic rotated 90 degrees like this.

If that doesn't quite do it,
mentally slide the batteries around to be on the left hand vertical.
