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.
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.
Ohm
Resistor is a current a insulator is a not conductive and conductors can conduct.
Those are the materials we loosely call "conductors".
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'.

Superconductors have no resistance, making them the best conductors. Semiconductors have moderate resistance. Conductors have low resistance, making them better conductors than insulators, which have high resistance, making them the poorest conductors.
ALL resistance are conductors. just the magnitude value changes
Superconductors have no resistance. Conductors have low resistance, semiconductors have intermediate resistance, and insulators have high resistance.
The resistance of pure metallic conductors increases with temperature, because the resistivity of these conductors increase with temperature.
Conductors have low resistance to the flow of electric current. The resistance of a conductor depends on its material, length, and cross-sectional area. Materials like copper and silver have low resistance, making them good conductors of electricity.
Materials with low resistance are called conductors. Conductors allow electricity to flow easily through them due to their low resistance. Metals such as copper and aluminum are examples of good conductors.
Conductors.
Good conductors have low resistance. A low resistance allows for the easy flow of electric current through the material. Materials like metals are good conductors because they have many free electrons that can move easily in response to an electric field.
Conductors have resistance due to collisions between free electrons and atoms within the material. This resistance causes energy to be lost in the form of heat when current flows through the conductor. The resistance value depends on the material and dimensions of the conductor.
It is called resistance Good conductors have a bad resistance While bad conductors or insulators have good resistance against the flow of electricity
No, the resistance of an insulator is very high.
