WebMar 14, 2024 · The resistance in a wire increases as: the length of the wire increases the thickness of the wire decreases How does the thickness of a wire affect the current? the thickness of the wire decreases An electric current flows when electrons move through a conductor, such as a metal wire. WebSep 12, 2024 · The resistance can be found using the length of the wire L = 5.00m, the area, and the resistivity of copper ρ = 1.68 × 10 − 8Ω ⋅ m, where R = ρL A. The resistivity and current density can be used to find the electrical field. Solution First, we calculate the current density: J = I A = 10 × 10 − 3A 3.31 × 10 − 6m2 = 3.02 × 103 A m2.
WebSep 7, 2024 · The answer is "it depends." Wires are not ideal, but in some cases the difference will be negligible. It all depends on your particular circuit and its design. As an answer to a question you did not ask, you might be interested in 4-wire sensing. 4-wire sensing is a process used for measuring very small resistance. WebDec 5, 2024 · Does wire length affect current? Current flow will decrease. Wire has resistance. The longer the wire, the higher the resistance, the less current will flow. What effect does passing current through a coil of wire have?
WebAug 2, 2016 · The difficulty is that the amount of flux affecting the wire loop depends on neither the thickness nor (directly) the length of the wire in question, but the area enclosed by the wire: The flux used to decide how much current is induced is that the wire wraps around, rather than some other quantity measured through the region of space that the ...
