PPT-Current and Resistance Current Density and Drift Velocity

Perfect conductors carry charge instantaneously from here to there Perfect insulators carry no charge from here to there ever Real substances always have some density n of charges q. Comparing shocks from static electricity and electric currents is like comparing apples and oranges, they are similar but quite different at the same time..
