Hence among the given materials, following are conductors: Silver, Copper, Aluminium, Nichrome, Graphite, Mercury, Manganin Note: Graphite is not a metal, but still a conductor of electricity, as it has delocalized (free) electrons, which help in conduction.

What are 10 examples of conductors?
10 Electrical Conductors Silver. Gold. Copper. Aluminum. Mercury. Steel. Iron. Seawater. 24 Nov 2019 What are some examples of conductors? 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, …
What are four poor conductors?
What are 4 poor conductors? A poor conductor means that the substance will not easily conduct heat or electricity (or both) as easily as a conductor. Some other examples of poor conductors of electricity are mica, paper, wood, glass, rubber, Teflon, etc. Some examples of poor conductors of heat are air, lead, etc. Hope this helps.
Which of these is a good conductor?
Similarly, the substances that have high electron mobility are known as good conductors. And, the ones which do not have good electron mobility are known as bad conductors or insulators. Metals like copper, gold, silver, steel, aluminium and brass and some of the most common and best conductor of electricity.
What are 4 examples of a conductor?
Examples of conductors include metals, aqueous solutions of salts (i.e., ionic compounds dissolved in water), graphite, and the human body. Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.

What is conductor with example?
Conductors are defined as the materials or substances that allow electricity to flow through them. Also, conductors allow heat to be transmitted through them. Examples of conductors are metals, the human body, Earth and animals. The human body is a strong conductor.
What are 3 types of conductors?
There are four types of conductors, namely, good conductors, semiconductors, resistors and non-conductors.
What is a conductor List 2 examples?
Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
What are conductors for Class 6?
Conductors are objects that allow electricity to pass through them. Copper, gold, silver and iron are good conductors of electricity.
Is metal a conductor?
Metals are good conductors (both of heat and electricity) because at least one electron per atom is free: i.e., it is not tied to any particular atom, but is, instead, able to move freely throughout the metal.
Which is a good example of conductor?
Examples of Conductors Copper, Brass, Steel, Gold, and Aluminium are good conductors of electricity.
What are the good conductors?
What Metal is the Best Conductor 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. ... Copper. One of the most commonly used metals to conduct electricity is copper. ... Aluminum.
Which is not an example of a conductor?
Sulphur, Phosphorus, Wood are non-conductors of electricity due to no presence of free electrons in outermost shell.
What is the best conductor of electricity?
The best electrical conductor, under conditions of ordinary temperature and pressure, is the metallic element silver. Silver is not always an ideal choice as a material, however, because it is expensive and susceptible to tarnishing, and the oxide layer known as tarnish is not conductive.
Why is electrical conductivity dependent on electron movement?
Electrical conductivity is dependent on electron movement because protons and neutrons don't move—they are bound to other protons and neutrons in atomic nuclei. Conductors Vs. Insulators. Valence electrons are like outer planets orbiting a star.
How does the shape of a material affect its conductivity?
The shape and size of a material affect its conductivity. For example, a thick piece of matter will conduct better than a thin piece of the same size and length. If you have two pieces of a material of the same thickness but one is shorter than the other , the shorter one will conduct better because the shorter piece has less resistance , in much the same way that it's easier to force water through a short pipe than a long one.
Which substances are insulators?
Inorganic substances like metals and plasmas that readily lose and gain electrons top the list of conductors. Organic molecules are mostly insulators because they're held together by covalent (shared electron) bonds and because hydrogen bonding helps stabilize many molecules. Most materials are neither good conductors nor good insulators ...
Is a material a conductor or an insulator?
Most materials are neither good conductors nor good insulators but somewhere in the middle . These don't readily conduct but if enough energy is supplied, the electrons will move. Some materials in pure form are insulators but will conduct if they are doped with small quantities of another element or if they contain impurities.
Do electric currents flow through insulators?
Electric charges do not flow freely through insulators. This is an ideal quality in many cases—strong insulators are often used to coat or provide a barrier between conductors to keep electric currents under control. This can be seen in rubber-coated wires and cables. The most effective electrical insulators are:
Is ceramic a superconductor?
For example, most ceramics are excellent insulators but if you dope them, you can create a superconductor. Pure water is an insulator, dirty water conducts weakly, and saltwater—with its free-floating ions—conducts well.
