Discussion Overview
The discussion revolves around the application of nodal analysis in circuit analysis, specifically addressing a homework problem involving voltage calculations in a circuit. Participants share their attempts at solving the problem and seek validation of their results.
Discussion Character
- Homework-related
Main Points Raised
- One participant initially claims to have calculated a voltage of 3V but questions its correctness.
- Another participant asserts that the 3V result is incorrect and requests the first participant to show their work for further assistance.
- A participant points out a potential discrepancy in the formulas used, suggesting that V2 should equal V1 plus 18V based on the circuit diagram.
- After acknowledging the correction, the participant recalculates and proposes new voltage values: V2 = 4.5V, V1 = -13.5V, V3 = 11.25V.
- Another participant confirms that the recalculated answer of 11.25V is correct.
- A final participant expresses gratitude for the assistance received during the discussion.
Areas of Agreement / Disagreement
The discussion shows some disagreement regarding the initial voltage calculation, but later contributions indicate a resolution with the corrected values. However, the initial uncertainty about the correctness of the first calculation remains unresolved.
Contextual Notes
Limitations include potential misunderstandings of the circuit diagram and the need for clarity in the formulas used, which may depend on specific definitions or assumptions not fully articulated in the discussion.

Your formula (1) doesn't seem to match the circuit diagram. Shouldn't V2 = V1 + 18V?

Ah, you're right. Thanks.
If that's corrected and propagated down... I get
V2 = 4.5V, V1 = -13.5V, V3 = 11.25V
So the answer is 11.25V?
