Figure 1 shows the junction of three wires, X, Y and Z, in a circuit.

A circuit diagram showing a junction of three wires labeled X, Y, and Z. Wire X enters the junction from the left with a current of 7.4 A, indicated by an arrow pointing towards the junction. Wire Y exits the junction pointing upwards and to the right with a current of 4.1 A, with an arrow pointing away from the junction. Wire Z exits the junction pointing downwards and to the right with an arrow pointing away from the junction.

The current in wire X is 7.4 A. The current in wire Y is 4.1 A.

Calculate the current in wire Z.
