The figure below shows a collection of wires. The currents at the numbered points are: I1 = 2.4 mA right; I2 = 3.6 mA down; I3 = 0.60 mA right; I4 = 4.0 mA up; and I5 = 1.6 mA up. i.imgur.com/SCyljHG.png What is the current at point A (size and direction)?

I think its 4.4mA... Cause A=2.4+3.6-1.6 (-1.6 because I5 is acting in opposite direction)
