Nodal analysis voltage confusion

Click For Summary
SUMMARY

The discussion centers on the confusion regarding nodal analysis in electrical circuits, specifically the voltage across resistors R1 and R2. The voltage across R2 is defined as vT-0 = vT, while the voltage across R1 is expressed as vT-Vs1. Participants seek clarification on the nodes involved in these voltage measurements and the application points of the voltage source Vs1. The circuit diagram provided specifies the connections for Vs1, which is crucial for accurate analysis.

So the voltage across the R2 resistor is given as vT-0 = vT

But then the voltage across the R1 resistor is given as "vT-Vs1"
I'm not sure which two nodes the voltage across R2 involves. Is it the same as R1?

Also, I am not sure of the voltage source vs1. Across which two points does it apply?
