Conductors with almost zero resistance are called superconductors. They are able to carry electrical current with no energy loss due to resistance, making them highly efficient in a variety of applications.
Normal conductors have resistance which restricts the flow of electricity and wastes some of the energy as heat. The resistance increases with the length of the conductor. Superconductors have close to zero or zero resistance and a few other properties, but the resistance is the most important one because it means electricity can flow more efficiently through it. The drawback is that all the superconductors we know of today have to be cooled down to EXTREMELY low temperatures to achieve superconductivity.
When cooled, certain materials like superconductors can exhibit almost zero resistance to electric current. This phenomenon allows for the efficient flow of electricity with minimal energy loss, making superconductors valuable for various applications such as in electronics, medical devices, and energy storage.
Some electrical conductors become superconductors when cooled to near absolute zero. This means they can conduct electricity with zero resistance, allowing for efficient electrical transmission and various technological applications.

Superconductors have the lowest resistance of all materials, with resistance dropping to zero when they are cooled below a certain critical temperature. Conductors have lower resistance than semiconductors and insulators, which have significantly higher resistance and do not conduct electricity as effectively.
Time constant in an RC filter is resistance times capacitance. With ideal components, if the resistance is zero, then the time constant is zero, not mattter what the capacitance is. In a practical circuit, there is always some resistance in the conductors and in the capacitor so, if the resistance is (close to) zero, the time constant will be (close to) zero.
Not all 'short circuits' are 'dead-shorts' -i.e. the resistance between the two conductors (or a conductor and earth) is not necessarily zero ohms -especially when the insulation between them has not completely broken down. The actual resistance is called the 'fault resistance'.

A superconductor truly has zero electrical resistance.It took scientists a half century to explain why, so this answer will omit the explanation of the effect.

No. A conductor is a good carrier of electricity or heat. A superconductor is a material in which the resistance to electrical flow is zero. Silver and copper are fairly good conductors, but some energy is lost.
conductorCobalt is a metal. Metals are good conductors of heat and electricity.
