# why is 220v ac more dangerous then 22ov dc?

because in ac this is

V=(2)1/2Eo

=1.414x220 i.e.314v.

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 :)

hmm thnx to all.... :) got the answer... for Rishabh...

AC IS NOT ALWAYS MORE DANGEROUS THAN DC, BECAUSE WHEN  A PERSON GETS A SHOCK BY AC WIRE ,THE WIRE WILL LEAVE HIM BUT WHEN TOUCHES A DC WIRE HIS BODY STICKS TO THE WIRE.

RMS value of 220v ac is greater than same dc

220 gets multiples by root 2 as RMS Current is shown by the device

220 v AC has maximum value =(2^1/2) ?220 =311v so it gives instantaneous shock of 311v while 220 v gives only of 220 v that's why 220v AC is more dangerous than 220v dc

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.
