Finding V1 and V2 in a Circuit Analysis for Scientists

[wudingbin]

Please take a look at the question and help me find the v1 and v2.
thank you!

any attempt? Any ideas? Any specific problems?

Take each source on its own...also known as superposition. When taking a specific source in account...short all other voltage sources and open all other current sources. Find voltage from each source and add all together. Piece of cake.

Let us know what you get.

Hi wudingbin. Just so we're all on the same page with this problem, can you tell us what convention your text/teacher uses for crossing wires?

- Some adopt the convention of no connection by default (with a junction, if required, shown as a small filled in circle).

- Others adopt the convention of a connection by default (with non connected wires shown using a small "overpass" symbol).

So which convention are you using?

BTW...that bottom 2 ohm resistor on the left hand of the circuit...slide that down about a half inch to match the other loads...it is lifted up just to add more confusion. Un-confuse it.
