I think this might useful to escape from Physics sir(Arul)
Explanation:
So many devices around us that made our quality of life so much better are electronics. The electronic devices rely of the control of the flow of electrons. Depending on the material's ability to conduct electricity we classify them as insulator, conductor, semiconductor and superconductors.
Insulators block electric current from flowing. This is useful to protect circuit from short wire or keep
us from harmful high voltage Common insulators around us are air, pure water, glass, and etc
Conductors are those that can conduct electricity Wires are made out of conductors. They easily
conduct electricity and enable us to connect the current from one place to another. Example of such materials are copper, silver, tap water, and generally most of materials we consider metals.
Semiconductor is somewhere between conductor and insulator Depending on the purity, voltage, and even temperature semiconductors can conduct electricity or not This makes semiconductors very valuable material for electronics. They can manipulate the current flow!
Superconductors are a novel material that shows zero resistance So you can run current through and you won't lose any energy! Sounds like a great idea to save energy, so why not just use superconductors instead of conductors? There is a catch. Superconductors are normally conductors They become superconductor in only certain situation. Majorly superconductivity depends on temperature, current and magnetic field. This is not all. Some are only superconductors in very high pressure So while we hope to be able to use these someday, it is still very hard to implement this.
