The larger the diameter of a wire, the less resistance it will have and the more current it can carry.

Question

Quizplus · Accepted Answer

This is because a larger diameter wire provides a larger cross-sectional area for the current to flow through, which results in less resistance. Additionally, Ohm's law states that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R) (I = V/R). Therefore, with less resistance, the wire can carry more current.

The Larger the Diameter of a Wire, the Less Resistance
