For DC circuits:
R = l*p / A
R - resistance
l = length of the conductor
p = electrical resistivity
A = the cross sectional area
Calculating for AC, and especially three phase power becomes much more complicated. If you need to know more for AC, let me know specifics.

Do conductors have low resistance?
Conductors have low resistance. Recall Ohm's law. The higher the conductor resistance, the greater the voltage drop along the conductor, and the less voltage that is available for the load. The conductor resistance is a resistance in series with the load. Also, higher conductor resistance results in more electrical power being converted into heat, warming up the conductors. This is calculated with the formula P=I2R. The greater the resistance, the greater the power wasted heating the conductors.
Electrical resistance is a property of conductors that is measured in units of?
Ohm
What is the difference between resistance and insulation?
Resistor is a current a insulator is a not conductive and conductors can conduct.
What is a material that allows electron to flow easily or with little resistance?
Those are the materials we loosely call "conductors".
What is fault resistance?
Not all 'short circuits' are 'dead-shorts' -i.e. the resistance between the two conductors (or a conductor and earth) is not necessarily zero ohms -especially when the insulation between them has not completely broken down. The actual resistance is called the 'fault resistance'.

What type of resistance do conductors have?
Conductors have a (low) Electrical resistance.
Good conductors have a high resistance or low?
Good conductors have low resistance
The relationship between resistance and conductors is?
ALL resistance are conductors. just the magnitude value changes
For most conductors as their temperature increases their resistance?
The resistance of pure metallic conductors increases with temperature, because the resistivity of these conductors increase with temperature.
Why do you call metals as poor conductors?
Metals are poor conductors as they offer resistance to the flow of electrons however super conductors offer less or no resistance
What is the formula of total amps?
There is no 'formula' which defines the ampere. The ampere is defined in terms of the resulting force between two parallel, current-carrying, conductors, due to the magnetic fields surrounding those conductors.
What are the materials have low resistance?
Conductors.
What is the characteristic of a material that hinders electron flow?
It is called resistance Good conductors have a bad resistance While bad conductors or insulators have good resistance against the flow of electricity
Which has a higher resistance insulators or conductors?
No, the resistance of an insulator is very high.
Do insulators have lower resistance than conductors?
On the contrary, insulators have higher resistance than conductors. Resistance refers to resisting a flow of electricity, making it more difficult for electricity to flow. Conductors conduct electricity, they make it easy for electricity to flow. Insulators prevent the flow of electricity.
What is the formula to find resistance force?
Work force plus effort force
