What is the resistance of a 4.9 m length of copper wire 1.9 mm in diameter?
Question: What is the resistance of a 4.9-m length of copper wire 1.9 mm in diameter? The resistivity of copper is 1.68×10−8Ω⋅m.
Which wire has more resistance thick or thin?
The relationship between resistance and wire length is proportional . The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current.
What is the weight of a copper cable?
Copper wire weight decreases as the wire gauge goes up. A 0000 gauge wire will weigh 640.5005 lbs per 1000 feet, while a 40 gauge wire weights 0.0299 lbs per 1000 feet.
What is the diameter of a copper wire?
The diameter of the metal conductor in a 12-gauge copper wire is 0.0808 inches; of a 14-gauge wire is 0.0641 inches.
What is gauge copper wire?
Wire Gauges. Wire gauge is denoted by a whole number ranging from 0000 to 40; decreasing in diameter as numbers get larger. Household wiring for 120-V circuits is almost always 12- or 14-gauge copper wire, depending on the current load and length of the circuit. The diameter of the metal conductor in a 12-gauge copper wire is 0.0808 inches;
