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.
What makes a material a conductor or an insulator?
What makes a material a conductor or an insulator? Simply put, electrical conductors are materials that conduct electricity and insulators are materials that do not. Whether a substance conducts electricity is determined by how easily electrons move through it.
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 ...
Can a material be an insulator?
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. For example, most ceramics are excellent insulators but if you dope them, you can create a superconductor.
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:
What are 3 examples of conductors?
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.

Of all the materials, the top three are silver, copper and aluminum. Silver is known to be the best conductor of electricity but it is not widely used for economic reasons.
What are conductors 4 examples?
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.
Which are good conductors?
Metals, especially silver, are good electrical conductors. Copper is cheaper than silver, so it is made into millions of miles of electrical wiring every year. Materials like glass and plastic are poor electrical conductors, and are called insulators.
Is copper a conductor?
And since copper wire has a low level of resistivity, it’s a fantastic electrical conductor . Copper is also an incredibly flexible material. Electrical connectors and wiring need to handle large loads of electricity at a time, but most metals that take on these loads don’t bend easily.

Therefore, based on the conductors’ definition due to their resistivity, they can be bifurcated into two categories. Low resistivity/high conductivity materials. High resistivity/low conductivity materials.
Why can electrons move freely inside conductors?
Therefore, when we apply a potential difference across the conductor, due to high conductivity and of course, low resistance, electrons can freely move inside the conductors.

A semiconductor is a material whose electrical conductivity falls between that of a conductor and an insulator. Example, Germanium and Silicon
How does a charge transfer to an element affect the movement of electrons?
When a charge is transferred to such an element, it gets distributed across the entire surface of the object, which results in the movement of electrons in the object. The charges transferred to an electrical conductor distribute until the force of repulsion between electrons in areas of excess electrons is decreased to the minimum value. When such an object is brought in contact with another conductor, the charge gets transferred from the first conductor to the other until the overall repulsion due to charge is minimized.

How does conduction work?
Conduction Defined in Simple Terms. Conduction is one of the ways that heat can transfer from one place to another. Conduction occurs when energy is transferred from one atom or object to another. It takes place through either heat or electricity. Conduction can occur in liquid, gaseous or solid objects. For conduction to take place between two ...
Why does conduction occur between atoms?
This is because conduction does not cause materials to be displaced.

Electrical conduction occurs when particles that are electrically charged move through some type of medium to produce electrical energy.
Why does salt conduct electricity?
The water would conduct the electricity such that touching the device could result in electrocution. When table salt is dissolved in water, it can conduct electricity. That is because the water separates the sodium ions from the chlorine ions apart. If playback doesn't begin shortly, try restarting your device.
