Homework Statement



http://images.4chan.org/sci/src/1340320682704.jpg

I am to write KCL equations for this circuit. Why is it that the current flowing AWAY from Node C is written as V2(t). I thought that when a current was flowing AWAY from a node, the current would be -V2(t)??

Homework Equations





The Attempt at a Solution



My guess is this.

Normally a current flows from + to -. If this is true then:
> Current is negative when flowing away from a node and positive when flowing toward a node.

Unless the polarity is switched (like it is in the circuit diagram in which case, the sign if the current is switched? But i don't know if this is true or not. can anyone confirm or deny this?
