There is no such thing as 0Ω resistance.Surely if its 0 Ohms then it is not a resistor. It will not have any volts drop across when carrying current so cannot be defined as a resistor. Its a "jumper" or 'bridge".
Superconductors?There is no such thing as 0Ω resistance.
They're usually used as jumpers. I have a partial roll of 1/4W size. The marking is a single black band.Never heard of a 0 ohm resistor. You learn something every day
