You go to the NEC and look at the chart for developed length and the ambient temperature and the load factor and if it solid or stranded wire as stranded allows for more voltage

What is the value of the resistance when both length and diameter are double?
Doubling the diameter of a circular-section conductor will quadruple its cross-sectional area and, therefore, reduce its resistance by a quarter. Doubling the length of a conductor will double its resistance. So, in this example, the resistance of the conductor will halve.
A piece of wire 100 m long has a diameter of 1 mm with a resistance of 2 ohms calculate the resistance of the same wire 2 km long with the same current?
If the wire length is 100m and the Diameter is 1mm calculate the Resistance of wire?
What would the resistance of the wire if the resistance is 10 ohms be the same if it were twice as long?
The resistance of a conductor is directly proportional to its length, hence increasing the length twice will increase the resistance twice as well. Therefore the resistance will be 2*10 = 20 Ohms
Which conductor size has the largest diameter?
The largest conductor listed in the National Electrical Code is a 2000 kcmil.
What increases resistance in a wire?
Current (measured by an ammeter) and Voltage (measured by a voltmeter) R= V/I Resistance equals voltage divided by current ================================ That's wonderful, but the measurement doesn't "affect" the resistance of the wire. The factors that do "affect" the resistance ... i.e. determine what the resistance will be ... are -- substance of which the wire is composed -- dimensions of the wire: thickness and length.
What affects the resistance of an electric conductor?
The material from which the conductor is made, the length of the conductor, the diameter of the conductor and the temperature of the conductor are all things that impact its resistance.

Doubling the diameter of a circular-section conductor will quadruple its cross-sectional area and, therefore, reduce its resistance by a quarter. Doubling the length of a conductor will double its resistance. So, in this example, the resistance of the conductor will halve.
What would be the effect of resistance of a conductor of doubling its diameter?
doubles
What has the least amount of resistance a semi conductor insulator resistor or a conductor?
Traditionally, a conductor has the least resistance of the three, followed by the semiconductor and finally the resistor.
Do thick wires have high or low resistance?
Low resistance.AnswerSince resistance is inversely proportional to the cross-sectional area of a conductor, increasing the diameter ('thickness') of a conductor will reduce its resistance.For example, doubling the diameter of a circular-section conductor will quadruple its cross-sectional area, and reduce its resistance by one quarter.
A piece of wire 100 m long has a diameter of 1 mm with a resistance of 2 ohms calculate the resistance of the same wire 2 km long with the same current?
If the wire length is 100m and the Diameter is 1mm calculate the Resistance of wire?
When the diameter of a conductor is doubled what happens to its resistance?
Resistance will decreases... Because R is inversely proportional to Area of the conductor.AnswerIf the conductor has a circular cross-sectional area, then doubling the diameter will reduce the resistance to one quarter of its original distance. This is because area is proportional to the square of the radius, and resistance is inversely proportional to cross-sectional area.
How is electrical resistance decreased?
Ways to reduce electrical resistance: increase the diameter of the conductor, decrease or increase the temperature of conductor (depending on its thermal characteristics), decrease the length of the conductor. A change in the material out of which the conductor is made can decrease resistance, too. And there is the phenomenon of superconductivity. In a simple circuit the resistance can be lowered by adding resistors in parallel. The total circuit resistance will then decrease. You can also reduce resistance by substituting resistors of lower value, or by adjusting a potentiometer, or pot, to a lower value.
What would the resistance of the wire if the resistance is 10 ohms be the same if it were twice as long?
The resistance of a conductor is directly proportional to its length, hence increasing the length twice will increase the resistance twice as well. Therefore the resistance will be 2*10 = 20 Ohms
Which variable is inversely proportional to the resistance?
If you have a conductor ... say, a copper wire ... and you keep its diameter and temperatureconstant, then yes, its resistance will be directly proportional to its length.
How does the resistance of a wire vary with its area of cross section'?
Conversely, as the cross-sectional area of the conductor icreases, the resistance decreases, just as a pipe of large diameter offers less resistance to fluid flow than does a pipe of small diameter.
What will the current-carrying capacity be if a conductor has a diameter of one half inch but there is a nick in one section so that the diameter of that section is one fourth inch?
The resistance of such a conductor will be less than without such a nick. In other words, for the same voltage, you would get less current.
