The current through a 75w AC fan is 75/220=0.34 we feel this current.But the current through 20w,12V DC fan is 20/12=1.666A but we dont feel it why?

OpenStudy (radar):

You "don't feel it" cause the current is going to the fan. If the current is flowing thru you, you would "feel it". I = E/R and as you can see the body resistance would come into play. Don't quite understand the purpose of the statement???
