Answer / shivam
according to me...in ac , the wave is sinusoidal. the wave
goes to zero twice in one cycle. The person who got shock,
thus can be put away from the supply,,,,but in case of a dc
suppl,,, the supply is direct means wave is a straight
line, and doesnot go to zero anyhow.....thus dc is more
dangerous than ac

Answer / gerhard
Current passing through the body cause the muscle in the
body to contract which stops you from releasing the
conductor if the current passing through your dody is about
50mA. If a ac current of less than 30mA pass through your
body you may be given the chance to come free not only
because the current is low but also because with ac the
signal goes through the zero potential 100times in one
second at 50Hz supply. With a dc supply you will not have
the opertunity to come free as the signal does not go
through the zero potential giving you the break as what ac
does.

Answer / sumanta kumar nahak
because the dc is high rating voltage & constant so,DC is
dangerous.

Answer / nupurpatel
in DC source,its frequency is constant so that their current is high. in AC source,its frequency is sinosuidal form so that their current is fluctuate

Answer / touqheed
DC current is dangerous because , if we observe the graphical representatio of AC current and DC current flow then we can undrestand the flow of AC comes twice to zero in one cycle but where as in AC it will be regular of constant it doesn't cross the position of zero hence probability to escape from high voltage DC shock is ... 5%.

Answer / anand
220 dc mean 220dc..
but 220ac mean rms valu which is less than 220..
thats why dc is dangerous..

Answer / srilu
Since DC supply is continues where as AC supply is
discontinues (Sinusoidal or any other), a perticular
voltage is of DC effective(dangerous) other then that
perticular DC voltage
This is ONE of reason for using DC current for magnetic
field other then AC
