WebJul 1, 2024 · Current density (J) = 5 A/m 2 We know that, Current density (J) = I/A 5 = I/15 I= 5 × 15 = 75 A Hence, the current flowing through the wire is 75 A. Problem 4: Find the cross-sectional area of the wire if the current flowing through the wire is 4 mA and its current density is 0.25 A/m2. Solution: Given data, WebMar 2, 2024 · This is the case in the most conductive metals, such as silver, gold, and copper. Each has a single valence electron that moves with little resistance and causes a strong repelling reaction. Semiconductor metals (or metalloids) have a higher number of valence electrons (usually four or more).
