How do you calculate the resistance of a wire?
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).

How do you calculate copper resistance?
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.
How do you calculate resistance and resistance of a cable?
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.
How much resistance is in a copper wire?
Resistivity ρ Copper has a resistivity of 0.0171 Ohm · mm²/m and is, therefore, one of the best conductors for electric current (slightly behind pure silver).
Do wires have resistance?
Resistance of a wire is directly proportional to its length and inversely proportional to its cross sectional area. Thickness and length Electrical wires are made in such way that it can sustain with the respective potential difference and current flow through it. Resistance of a wire causes the flow of current.
Does copper have high resistance?
Copper has the best electrical conductivity of any metal, except silver. A good electrical conductivity is the same as a small electrical resistance….Good Electrical Conductivity.

What is the resistance of a wire?
The ohm is the common unit of electrical resistance, equivalent to one volt per ampere and represented by the capital Greek letter omega, Ω. The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor.
Does a thicker wire have more resistance?
The longer a wire is the more resistance it has due to the longer path the electrons have to flow along to get from one end to the other. The larger the cross sectional area, the lower the resistance since the electrons have a larger area to flow through. This will continue to apply no matter how thick the wire is.
Does a longer wire have more 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 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.
How does length of wire affect resistance?
From the graph it can be seen that the longer the piece of wire, the higher the resistance. Resistance is directly proportional to length as the graph gives a straight line through the origin.
What 4 things affect the resistance of a wire?
There are four factors affecting resistance which are Temperature, Length of wire, Area of the cross-section of the wire, and nature of the material.
Which of these will increase the resistance of a wire?
length – longer wires have greater resistance. thickness – smaller diameter wires have greater resistance. temperature – heating a wire increases its resistance.
What happens when we increase the length of wire shorten the length of wire?
A longer wire will eventually carry less current, because the resistance increases as the length increases. A shorter wire can carry more current than a longer wire.
