what is skin effect? why is it absentin dc system

Answer Posted / anonymous

In skin effect the current density is way more on the surface rather than in the core of the conductor..
Remember that skin effect is caused by eddy currents. We know that these eddy currents are induced by the alternating current.
This is obviously caused by the frequency of ac. So there's no skin effect in dc..
