21. For alternating currents ( AC ), the skin effect causes the resistance to increase with increasing frequency. 22. Skin effect causes the high frequency resistance of inductors to be many times their direct current resistance.23. The skin effect causes the effective resistance of a conductor to increase at higher alternating current frequencies. 24. At high frequencies there are also additional losses in the windings due to proximity and skin effect . 25. It may potentially cause an irritating skin effect and has been associated with atopic dermatitis in canines. 26. Even with a low loss dielectric, capacitors are also subject to skin effect losses in their plates. 27. Aluminum arsenide is poisonous if ingested and may cause gastrointestinal and skin effects and acute arsenic poisoning. 28. I can tell you from direct experience, microwaves do not penetrate deeply due to the skin effect . 29. Increased AC resistance due to the skin effect can be mitigated by using specially woven litz wire. 30. Another reason for using many thin conductors connected in parallel lies in avoiding the so-called Skin effect .
