What is a material with low resistance?
A material with low resistivity means it has low resistance and thus the electrons flow smoothly through the material. For example, Copper and Aluminium have low resistivity. Good conductors have less resistivity. Insulators have a high resistivity.
What material offers very low resistance to the flow of current?
Copper is considered an excellent conductor because it offers very little resistance.
What is the best material for conductors in terms of lowest resistance?
Aluminium occasionally and particularly copper are used for their low levels of resistivity. Most wire used these days for interconnections is made from copper as it offers a low level of resistivity at an acceptable cost.
What material is a low conductor of electricity?
Materials like glass and plastic are poor electrical conductors, and are called insulators. They are used to stop electricity from flowing where it is not needed or where it can be dangerous, such as through our bodies.
What is a metal with a very low resistance?
The extremely low resistivity (high conductivity) of silver is characteristic of metals.
Which of the following has very low resistance?
Detailed Solution Nichrome has low resistivity.
Which of following has very low resistance?
Detailed Solution. Nichrome has low resistivity.
Which of the following is very low resistance?
So that the steel offers very low resistance when compared to the other substances given. Steel has a large number of free electrons. So, the correct answer is “Option D”. Note: When compared to nichrome, water, and graphite, steel offers low resistance.
What are 5 good conductors?
The most effective electrical conductors are:
- Silver.
- Gold.
- Copper.
- Aluminum.
- Mercury.
- Steel.
- Iron.
- Seawater.
Which metal is the poorest conductor of electricity?
Solution : Bismuth and tungsten are poor conductors of electricity.
What are poor conductors?
A poor conductor is a material for which conductivity is low, yet sufficient to exhibit significant loss. To be clear, the loss we refer to here is the conversion of the electric field to current through Ohm’s law.
Which element is a poor conductor?
Nonmetals are poor conductors of heat and electricity, because electrons are not free to move. Nonmetals are found to the right of the stair-step line, except for hydrogen which is in group 1. Group 18 are the noble gases, which are all nonmetals.
What materials would not conduct electricity?
What materials Cannot conduct electricity? Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
Which materials are the best conductors of electricity?
Silver. The best conductor of electricity is pure silver,but to no surprise,it is not one of the most commonly used metals to conduct electricity.
What makes some materials good conductors of electricity?
Silver
What material conducts electricity the best?
The best conductor of electricity is silver followed by copper and gold due to its crystal structure and bonds. There is a lack of covalent character. It has lattice structure, which allow easier flow of electrons through it.
