Those are the so-called "superconductors" (there are several types), which have ZERO electrical resistance.
THE GUY WHO MADE ELICTRICITY IS MANKIND
Actually diamond is the best conductor of heat, and a diamond film substrate is used as a heat conductor in some microprocessors. Silver and copper are the metals more commonly used as heat conductors because of cost.
Stainless steel is not the best conductor. The best conductor is actually aluminum.
Silver is the best conductor of electricity among common metals, followed by copper. Both silver and copper have high electrical conductivity due to the mobility of their free electrons, which allows them to carry electric current efficiently.
A conductor is a substance that conducts heat or electricity.
A substance that is a good conductor of electricity typically has a high concentration of free-moving electrons, which allows electricity to flow easily through it. Metals, such as copper and silver, are examples of substances that are good conductors of electricity due to their high electron mobility.
Silver is the best conductor

It's not, there are materials that are better, like diamond.
This are the factor which affect resistance of a conductor (1). Area of conductor (2). Length of conductor (3) Temperature (4). Type or substance of material used in conducting the electricity.
