Question

Consider the juncion of three wires as shown in the diagram. (Figure 1) The magnitudes of the current density and the diameters for wires 1 and 2 are given in the table. The current directions are indicated by the arrows. Wire | Current density (A/mm²) | Diameter (mm) 1 | 1.9 | 1.5 2 | 6.0 | 3.5 Part A Find the current I? in wire 3. Express your answer in amperes to two significant figures. Call current out of the junction positive and current into the junction negative. I? = 16.1 A

Step 1

9 A/mm^2 r1 = 0.75 mm Calculate A1: A1 = π * (0.75)^2 A1 ≈ 1.76625 mm^2 Calculate I1: I1 = 1.9 * 1.76625 I1 ≈ 3.355 A Show more…
