How much current will be flowing through a $57.0 - \mathrm { m }$ length of copper wire with radius $0.0 \mathrm {~mm}$ if it is connected to a source supplying $62.0 \mathrm {~V} \text { ? }$ The resistivity of the metal is 1.68 × 10^-8 Ω ∙ m. A)0 A B)0 × 10⁸ A C)0 nA

Question

Quizplus · Accepted Answer

The radius of the wire is given as $0.0 \mathrm{~mm}$, which means the wire effectively has no cross-sectional area through which current can flow. Regardless of the voltage applied or the resistivity of the material, if there's no pathway for the current (due to the absence of a cross-sectional area), no current can flow through the wire.
