How do you calculate the resistance of copper wire?

Engineers often ask how to calculate the resistance of a cable, there is a very simple formula that works well within an ohm or so with copper cable.

19 ÷ by 2.5mm2 will

give you 7.6 ohms per km. ÷ by 1000 for resistance per meter. 19 ÷ by 4mm2 will give you 4.75 ohms per km.

What is the resistance of a long wire?

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 .

How do you calculate the resistance of a cable length?

Specific Resistance (”ρ”) is a property of any conductive material, a figure used to determine the end-to-end resistance of a conductor given length and area in this formula:

R = ρl/A

. Specific resistance for materials are given in units of Ω-cmil/ft or Ω-meters (metric).

What is the resistance of a 3m length of copper wire?

Copper wire of length 3m and the area of cross section 1. 7×10−6m2 has a resistance of

3×10−2m2 ohms

.

What is the resistance of a copper wire?

What is the resistance of a 5.4 m length of copper wire?

5.1×10−2Ω

Does a longer wire have more resistance?

First, the total length of the wires will affect the amount of resistance.

The longer the wire, the more resistance that there will be

. … When all other variables are the same, charge will flow at higher rates through wider wires with greater cross-sectional areas than through thinner wires.

How does the resistance of a wire depends on its length?

Resistance of a wire is directly proportional to the length of the wire. The resistance of a conductor depends on

the number of collisions which the electrons suffer with

the fixed positive ions while moving from one end to the other end of the conductor. … Therefore, a longer conductor offers more resistance.

What is the resistance of copper in ohms?

How much resistance should a wire have?

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.

What is the resistance of a 20.0 m long piece of 12 gauge copper?

So that’s 1.72 times 10 to the minus 8 ohm meters times 20.0 meters—length— multiplied by 4 divided by π times the diameter squared and this gives

0.104 ohms

is the resistance of this piece of wire.

How do you calculate copper in cable?

The copper weight is

calculated by the cross section of a cable x 9.6

and will be shown in kg / km. For example FLRY 1.50 mm2 has a copper weight of 14.4 kg / km (9.6 x 1.5).

What is the resistance of a 4.5 m length of this wire?

4.3×10−2Ω

What is the resistance formula?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law:

R = V / I

. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance R

_T

= 9 volts / 3 amps = 3 Ω.

What is the resistance of 16 gauge copper wire?

What is the resistance of a 3.5 m copper wire 1.5 mm in diameter?

3.3×10−2Ω

Does the length of the wire affect the current?

Current flow will decrease. Wire has resistance. The longer the wire, the higher the resistance,

the

less current will flow.

Can a 3.0 mm diameter copper wire have the same resistance as a tungsten wire of the same length?

Can a 3.0-mm-diameter copper wire have the same resistance as a tungsten wire of the same length?

Yes

, it can.

What happens to the resistance of a wire as its length increases?

Resistance = (Resistivity of material) *(length of material) / (cross sectional Area of material). From above equation we can say that, the resistance of

wire is proportional to its length

. Hence, resistance of wire will increase if length of wire is increased. So, resistance is directly proportional to length.

What type of wire would have the least resistance?

A short wire

has a lower resistance than a long one*. Resistance is directly proportional to the length of the path through which current flows: R ∝ L. This means the longer the wire, the more resistance.

On what factors does the resistance of the wire depend?

The factors on which resistance of the wire depends are : (i)

The length of the wire, resistance is directly proportional to the length of the wire

. (ii) The cross-section of the wire, resistance is inversely proportional to the cross-section of the wire.

How resistance of a wire depends on its specific resistance length and area of cross section?

Resistance increases with length and decreases with area of cross section, but specific resistance does not. It is a characteristic property of a material and in turn depends on the

collisions or scattering of electrons

.

On which factor resistance of a conductor depends?

The resistance of a conductor depends on

the cross sectional area of the conductor

, the length of the conductor, and its resistivity.

At what temperature the resistance of a copper wire will become?

4500C

.

How much copper is in a wire?

The copper content of nonmetallic (NM) cable is

between 55% and 56%

. Double-insulated heavy-duty home wiring.

What is the wire’s resistivity in Ω ⋅ M?

What is the cross-sectional area of A wire?

The cross-sectional area of the wire is the area of a circle of radius r:

A=πr2=π(d2)2

, where d is the diameter of the wire.
