Wires are sized depending on the amount of amperage they are expected to carry. High current required a large size wire and hence small amount of current only needs a small wire.
Thin wires
Thin Wires in the Voice was created in 1967.
Some wires are thick, others are thin. Wire thickness of up to about 30 mm diameter is used in electrical power distribution.
Thin wires have a greater resistance rhan thick wires. Imagine a straw. The thinner the straw. the less liquid can get through. Wires work the same way.
Thin wires have higher resistivity than thick wires because of increased electron scattering in thin wires. In thin wires, electrons collide more frequently with the wire's atoms or impurities, causing more resistance to the flow of current. Thicker wires have more free space for electrons to move through, resulting in lower resistivity.
I think thick wires are smarter
DUCTILITY
because
The metallic property of ductility allows it to be drawn into thin wires.
The property of metals to be drawn out into thin wires is called ductility. This allows metals to be stretched into wire or other thin forms without breaking.
The property is said to be ductile. Copper is said to be ductile as it is a metal than can be drawn out into thin wires, as used in electrical cables.
copper can be drawn into thin, long wires~`
