Current and area formula
WebDec 13, 2024 · Current density is a measure of the density of an electric current. It is defined as a vector whose magnitude is the electric current per cross-sectional area. In … WebThe current I = 20.0 A is given, and q = – 1.60 × 10 – 19 C is the charge of an electron. We can calculate the area of a cross-section of the wire using the formula A = πr 2, where r is one-half the given diameter, 2.053 mm.
