Click For Summary
SUMMARY

The forum discussion focuses on solving a node voltage circuit analysis problem to determine the values of V1, V2, and V3. The equations provided include a combination of resistances and voltage sources, specifically: (V1 + 15)/20 + (V1 - V2)/25 + (V3 - V2)/50 + (V3 - 10)/10 = 0, 18V1 - 12V2 + 24V3 = 50, and V2: (V2 - V1)/25 + V2/40 + (V2 - V3)/50 = 0. The user confirms that their approach to solving these equations is correct, indicating a solid understanding of node voltage analysis.

Hi, I am given a node voltage problem to find V1, V2, and V3 from this image below.


http://puu.sh/77Sg3.png

(v1+15)/20 + (v1-v2)/25 + (v3-v2)/50 + (v3 - 10)/10 = 0

18V1 - 12V2 + 24V3 = 50

V2: (v2-v1)/25 + v2/40 + (v2-v3)/50 = 0

17V2 - 8V1 - 4V3 = 0

15 = V3 - V1

Am I in the right track so far?
