when a resistor is connected to an independent source,the current flow in it depends on whether the power rating or resistance?

    resistance. Power comes later.

    \[V=IR=>I=\frac{V}{R}\]Looking at those equations (as @Shadowys said) you should see that current is inversely related to resistance. Power should be considered more of a result of the current and voltage: \[P=IV\]

    The power rating is how much heat the resistor can dissipate without melting, burning or otherwise wrecking itself.

    That's true also but I don't think that's what the question is asking
