Which type of current has the highest potential to irritate or damage the skin if used incorrectly?
What will be an ideal response?
Direct current has the strongest polar effects since the current flows in one direction and the duration is relatively long (> 1 sec). The cathode will attract Cl- and H+ ions, which creates an acidic reaction. The anode will attract Na+ and OH- ions, which creates an alkalytic reaction. These chemical reactions will irritate and damage the skin if the DC intensity is too high.
