        <<What will be the maximum current allowed for the resistor?>>
        I think manufacturers specify a maximum resistance value for a
so-called '0 ohm' resistor. For instance, a '0 ohm' jumper could be
specified as having an Rmax of 0.01 ohm. For a power rating of 0.1 W, hence,
it could take a max current of 3 A or so.

jumper?

        Hi All,
         
        I saw some people use one 0 ohms 0.1W 0603 resistor as jumper to
connect 5V to chip's power pin.  Is it a proper way?  What is the
disadvantage?  What will be the maximum current allowed for the
resistor? Since the resistor value is very small, does it mean a large
current is allowed to flow through the resistor to cross the 0.1w
limitation?
         
        Appreciate your comments..
