Conductors are materials that permit electrons to flow freely from particle to particle. An object made of a conducting material will permit charge to be transferred across the entire surface of the object.In conductors some electrons are unpaired so these electrons can move freely.

Explanation:

Conductors are materials that allow the movement of electrons. This means that the electrons in the material are free to move around and carry an electric charge. This ability to conduct electricity is what makes conductors useful in many applications.

Characteristics of Conductors:

1. Free Electrons: Conductors have free electrons that are not bound to any particular atom. These free electrons allow for the easy flow of electric current through the material.

2. Low Resistance: Due to the presence of free electrons, conductors have low resistance to the flow of electric current. This means that they can carry large amounts of current without overheating or melting.

3. Good Thermal Conductivity: Conductors also have good thermal conductivity, which means that they can transfer heat quickly and efficiently.

4. Examples of Conductors: Some examples of conductors include metals like copper, silver, and gold, as well as materials like graphite and saline solutions.

In conclusion, conductors are materials that allow the movement of electrons, which makes them useful for conducting electricity and transferring heat.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same:Electron Microscope Electron microscopes use electrons to illuminate a sample. In Transmission Electron Microscopy (TEM), electrons pass through the sample and illuminate film or a digital camera.Resolution in microscopy is limited to about half of the wavelength of the illumination source used to image the sample. Using visible light the best resolution that can be achieved by microscopes is about ~200 nm. Louis de Broglie showed that every particle or matter propagates like a wave. The wavelength of propagating electrons at a given accelerating voltage can be determined byThus, the wavelength of electrons is calculated to be 3.88 pm when the microscope is operated at 100 keV, 2. 74 pm at 200 keV and 2.24 pm at 300 keV. However, because the velocities of electrons in an electron microscope reach about 70% the speed of light with an accelerating voltage of 200 keV, there are relativistic effects on these electrons. Due to this effect, the wavelength at 100 keV, 200 keV and 300 keV in electron microscopes is 3.70 pm, 2.51 pm and 1.96 pm, respectively.Anyhow, the wavelength of electrons is much smaller than that of photons (2.5 pm at 200 keV). Thus if electron wave is used to illuminate the sample, the resolution of an electron microscope theoretically becomes unlimited. Practically, the resolution is limited to ~0.1 nm due to the objective lens system in electron microscopes. Thus, electron microscopy can resolve subcellular structures that could not be visualized using standard fluorescences microscopy.Q. As the accelerating voltage increases, the wavelength of electron as wave
