Problem

A junction connects three wires. Current

I_1 = 2.5\,\text{A}

flows toward the junction through wire 1, current

I_3 = 6.8\,\text{A}

flows away from the junction through wire 3, and the current

I_2

in wire 2 is unknown. Calculate both the magnitude and direction (toward or away from the junction) of

I_2

required for charge conservation at the junction.
