why 200 volt AC is more dangerous than 220 volt DC???

31/03/2018 0 0

current or voltage we measure for AC are alaways rms(root mean square) value not the actual magnitude so 220 volt ac(rms)= 220*sqrt(2)=311 volt

but 220 volt DC alaways gives the magnitude of curret or voltage =220 volt.

since 200volt AC have grater magnitude than 220volt AC ,so 220 volt AC is more dangerous.
