Well, 220 AC is the RMS value. Thus its Peak value will me more than this..it will be (root 2) X (220 V) = 311V

it means that if some one gets a shock by AC of 220, he will actually get a shock of 311 volts..but in DC of 220 V, it is its maximum value. Thus 220V AC is more dangerous than 220V DC .

Hope u get it :)

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.

? ? 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.

When we take current from 220V dc line,its voltage is restricted to an constant value 220V.But when the current will be taken from 220V ac line ,the voltage varries according to the characteristics of ac current.so the peak value of line voltage will be 311V(this value is constant).so the shock of this high value will be greater than the shock of the dc flow.for this reason 220V ac is more dangerous than 220V dc.
