      @alpino candy is the 10ohm resistor redundant here because current will flow through the 2v branch which has 0 resistance and no current flows through the 10ohm resistor because it has some resistance and hence is not a viable path for the current to flow? Or is there some other reason

    • @omerfaruk1351
      @omerfaruk1351 Před 3 lety +4

      i think, if we add V1-V2/10, then we have to add V2-V1/10 because the currents -left side and right side of the supernode- have to write properly. and sum of those 2 terms are 0. simply, we can say he wrote the shortly.

    I tried solving the practice problem of this sect from the same book... And whatever current you mention in the supernodes, all boils down to final equation as similar to single node... The redundant current, the 10 ohm resistance are all just to circulate their own current in their supernode... So whatever current enters 10 ohm, gets circulated back following the 2 v source, as like it had seperate path for that... But also it increases the nodal voltage and boosts the current. Aah it hurts thinking too much.

Think of it like a pipe where you have a black water and a white water... The black water flows seperately aside in that pipe without mixing, throu 10 ohm...
