Question

Which has less electrical resistance: a thin wire or a thick wire (of the same length and same material)?

Answer 1

For thin wire and thick wire we have same resistivity and length. So now, their resistance depends on the area of cross-section.
Resistance is inversely proportional to area of cross section.
Resistance increases with small area of cross section and decrease with large area of cross section.
thin wire has small area of cross section while thick wire has large area of cross section.
Thus thick wire will have less electrical resistance.

Answer 2

Thick wire would have less resistance than a thin wire.

Explanation:

• A dense wire has a larger cross- area,
• Whereas a thin wire has a smaller cross - area.
• As well, a conductor's resistance is inversely proportional to its cross- field.
• A thick metal (wire)  have less resistance than a thin metal (wire).

Conductor :- A conductor is an type or entity of material allowing charge to move in one or several paths. Materials made of metal are can conducers of electricity.
