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 ment by high resistance and low resistance on a meter?
On a multimeter, a high resistance would indicate a high Ohmic value and a low resistance would indicate a low Ohmic value. Specific values would be relative to device you are measuring.
What is a material that allows electron to flow easily or with little resistance?
Those are the materials we loosely call "conductors".
What is high resistance and low resistance?
Low resistance lets electrons through easy, and high makes it harder for them to pass. Basically electricity is harder to flow through high resistance and vice versa.
Good conductors have a high resistance or low?
Good conductors have low resistance
What type of resistance do conductors have?
Conductors have a (low) Electrical resistance.
What are the materials have low resistance?
Conductors.
What kind of marterials have low resistance?
the best conductors with low resistance are silver, copper, gold, aluminum (best to least best)
What is the term for materials that have very low themal energy and resistance?
conductors?
Is something that has low resistance conductors?
Yes, because anything that has low resistance definately have the ability to conduct much better than that of higher resistance. Resistance simply means the opposition to the flow of electrons in a conductor.
Why do spark plug wires have resistance?
All wires have a resistance, as does everything else in the universe. Conductors like metal and carbon generally have low resistances where as non conductors have a very high resistance. Think of it like friction, but electric.
Do conductors have high or low current?
Low resistance. Think of Ohm's law. Voltage drop is directly proportional to resistance. The higher the resistance, the higher the voltage drop, and the less voltage that is available for the load. Think of conductor resistance as a resistance in series with the load. Also, higher conductor resistance means more power lost, going to heating the conductors. The "line loss" formula is P=I2R. The greater the resistance, the greater the electrical power being converted into thermal power heating the conductors.
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
Does abrasion affect hardness?
No. Steel and mercury are both good conductors (low resistance). Diamond and rubber are both insulators (high resistance).
