Best ResponseYou've already chosen the best response.0i need to assign the 2 nodes next to Va as V1 and V2?

Best ResponseYou've already chosen the best response.0yea i think i got it, its very close to my experimental value.

Best ResponseYou've already chosen the best response.1It's easy, summing currents leaving from super node ( the branch with voltage Va) \[\frac{V_aE_1}{R_1}+\frac{V_a0}{R2}+\frac{V_a0}{R3}+\frac{V_aE2}{R4}=0\]
