Hi. Is the resistance of a charged cable different compared to a cable with zero net charge? If it is charged negatively, one could argue that now there are more carriers for the current, so the resistance should be smaller (similarly to water that becomes more conductive if ions are added). On the other hand, more particles might increase scattering which should increase resistance. Or can we just argue that by linearity, this superposition of charges doesn't affect the current at all?
