The electric field in a uniform wire is related to the potential across the wire, $\Delta$ V, and the length of the wire, $l$ , by A)$\Delta$ V· $l$ B) $\Delta$ V/ $l$ C) $l$ /$\Delta$ V. D) $l$ ²/$\Delta$ V.

Question

Quizplus · Accepted Answer

The electric field in a uniform wire is given by the potential difference (voltage) across the wire divided by the length of the wire, hence $E = \frac{V}{l}$.
