Which property of wires increases when their diameter is thicker?

When the diameter of a wire is thicker, its current carrying capacity increases. This is due to the fact that a larger diameter provides more surface area for the flow of electric current. As the cross-sectional area of the wire increases, it allows more electrons to pass through simultaneously without increasing the resistance significantly.

Additionally, thicker wires can dissipate heat more efficiently, which is crucial for preventing overheating during the conduction of current. This enhanced current carrying capacity is an essential consideration in electrical engineering and circuit design, especially in applications where high currents are involved.

The other properties mentioned, such as electrical resistance, voltage loss over distance, and inductance, either remain relatively constant or are less positively affected by a thicker wire compared to the direct relationship seen with current carrying capacity.
