What is the resistance of 1000 ft of No 12 House wire?
What is the resistance of 1000 ft of No 12 House wire?
Consider this: One thousand feet of 14 AWG solid wiring has a resistance of 2.53 ohms. The same length of 12 AWG has a resistance of 1.59 ohms.
What is the resistance for 1000 of 4 0 AWG copper?
Gauge, weight, circular mils and electrical resistance in copper wire.
| AWG Gauge* | Area (Circular Mils) | Electrical Resistance (Ohms/1000 ft) |
|---|---|---|
| at 149oF (65oC) | ||
| 0000 (4/0) | 212000 | 0.057 |
| 000 (3/0) | 168000 | 0.073 |
| 00 (2/0) | 133000 | 0.092 |
How do you calculate the resistance of a wire?
To calculate the resistance of a wire:
- Find out the resistivity of the material the wire is made of at the desired temperature.
- Determine the length and cross-sectional area of the wire.
- Divide the length of the wire by its cross-sectional area.
- Multiply the result from Step 3 by the resistivity of the material.
What is the resistance of 1000 feet of #16 AWG copper wire?
Common Wire Gauges
| AWG wire size (solid) | Diameter (inches) | Resistance per 1000 ft (ohms) |
|---|---|---|
| 18 | 0.0403 | 6.385 |
| 16 | 0.0508 | 4.016 |
| 14 | 0.0640 | 2.525 |
| 12 | 0.0808 | 1.588 |
How much resistance is too much in a wire?
Ideally, the resistance should be 2000 Ω, but due to the existence of a wire, the measured resistance is 2000.01693 Ω, it’s less than 10 parts per million higher, nearly undetectable.
How much resistance is considered a short?
zero
In the case of a short, the resistance is typically considered to be zero. Dividing a non-zero number by a value that approaches zero yields a value that approaches infinity!
What is the resistance of 1 000 feet of #16 AWG copper wire?
How does length of wire affect resistance?
The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. The relationship between resistance and wire length is proportional .
