A no resistance conductor is a material that allows electric current to flow through it without experiencing any resistance. This means that there is no loss of energy as the current moves through the conductor, resulting in efficient and fast flow of electricity.
Current flows through a no resistance conductor due to the movement of electrons. In this type of conductor, the electrons are able to move freely without encountering any obstacles or resistance. This allows for a smooth and continuous flow of electric current.
The effect of current flow through a no resistance conductor is the generation of a strong magnetic field. Since there is no resistance, the electrons can move at high speeds, creating a powerful magnetic field around the conductor. This effect is used in devices such as electromagnets and electric motors.
Some examples of no resistance conductors include superconductors, which are materials that exhibit zero electrical resistance at very low temperatures. Other examples include certain metals, such as copper and gold, which have very low resistance and are commonly used in electrical wiring.
No, it is not possible for a conductor to have zero resistance at all temperatures. Superconductors, which have zero resistance, only exhibit this property at extremely low temperatures. As the temperature increases, these materials will eventually start to exhibit resistance. This phenomenon is known as the critical temperature of a superconductor.
