Problem
During a 3.0 s interval, 0.90C of charge flows into a junction through wire A. Wire B carries a current of 0.20A away from the junction, and wire C carries an unknown current into the junction. Determine both the magnitude and the direction (into or out of the junction) of the current in wire C.
