why "I" is negative??
i know that KCL says that the sum of the currents that goes in
equals the sum of the currents that goes out
here i dont know what current goes into the node
and what current goes out??
i dont know how you decided the direction of each current
i am new to this stuff
and i think that the "I" current is pointed up
so it goes into the node
the second current the goes threw "R1" also come into the node
because the currect goes from the plus of the battery to minus of the battery
where did i go wrong??
i cant see the conventions here
i cant see how the currents flow using these conventions
in what case we have e-v and in what v-e
???
