What is the resistance of an aluminum wire?
Electrical resistance in plain copper or aluminum wires.
| Cross Sectional Area (mm2) | Resistance (ohm/km) | |
|---|---|---|
| Copper | Aluminum | |
| 1.0 | 17.2 | 26.5 |
| 1.5 | 11.5 | 17.7 |
| 2.5 | 6.9 | 10.6 |
How do you calculate the resistance of aluminum wire?
CALCULATION OF CABLE RESISTANCE
- Hence R = 22.5/10 = 2.25 Ohms per km.
- Length of conductor = 500m =500/1000 = 0.5km.
- Therefore resistance of copper conductor = 2.25 x 0.5 =1.125 Ohms. Similarly for Aluminium,
- R = 36/S(c.s.a)
- Again S = 10mmsq.
- Hence R = 36/10 = 3.6 Ohms per km.
- Length of conductor = 0.5km.
Does aluminum wire have more resistance?
This difference is highly relevant for power cables. To attribute to an aluminium conductor the same resistance as a copper conductor, the cross-sectional area of the aluminium conductor must become larger to compensate for aluminium’s higher electrical resistivity. Corrosion is not an issue for copper.

Why Aluminium is not used in electric wires?
Creeping: When electricity flows through wire, the wire heats up. Aluminum wire expands more than copper when it heats up. When aluminum wiring rusts, the white oxide is not a very good electrical conductor. It does interfere with the flow of electricity, and again, can cause overheating.
Is aluminum wiring a deal breaker?
Aluminum wiring. Aluminum wiring, which was popular during the Vietnam War era, isn’t terribly common these days. But if your potential home has it, it could mean big trouble. “Problem is, aluminum expands and contracts in the heat more than copper, which causes the connections to loosen up, and then you get fires.”
What is thee resistance of an aluminum rod 3.0 m long and 1.0 cm in diameter if this rod is stretched to a form a wire 0.01 cm in diameter What is its resistance?
the resistance of a rod with a length of 3.0m and a diameter of 1.0cm is 56.0 ohms. of this rod is stretched to form a wire with a diameter of 0.01cm, what is its resistance? assume that in the process of stretching the rod, its volume did not change. R 2 = 56 ⋅ 1 4 0.0 1 4 = 5.6 G Ω .
What is the electrical resistance of aluminum wire?
Electrical resistance in single core conductors: values are based on electrical resistivity for copper 1.724 x 10-8 Ω m (0.0174 μΩ m) and electrical resistivity for aluminum 2.65 x 10-8 Ω m (0.0265 μΩ m) AWG, diameter mil, circular mil, diameter in mm and area in mm 2
Which is larger copper wire or aluminum wire?
For the same conductivity aluminum wire is about two gauges larger than copper wire. The table above only lists the AWG standard. The wire size is different between the American Wire Gage [AWG] and the British standard.
