Answer / tahir saifi

BEST ANSWER ..both a.c and d.c are dangerous..but the chances of being safe is more in case of a.c..because a.c is flowing with pulsating means current flows in
positive cylce and negative cycle. when ever positive cycle
complete , alternating currrent come to zero value and if a person is strong enough to pull his hand then only he can be safe other wise he may die because of heart faliure.. but in case of d.c ..d.c attracts the person and repel after it absorb all the blood of his body..
...if we have low voltage a.c as well as d.c then a.c is more dangerous..because a.c frequency 50/sec and 3000/mint but heart beat is 72/mint so a.c can cause heart failure
.. but such a low level d.c is not strong enough to attract a person with vry high force, a person is strong enough to ovr come this force

Answer / murali

in a.c magnitude of electrical quantity keeps changing for
every instant where as in d.c it is constant.

Answer / hero

As Ac consist of sinusoidal waveform of certain frequency
say 50 hz so wen human get shock by AC current source it
has a chance to get rid of shock during negative cycle of AC
waveform but In case of DC since der is no frequency so
there is no chance of getting rid of current..!

Answer / srikanthreddy

k.i'll agree but, do u know dat the current at frequency 50-
60hz is more dangerous when compared to current at 1000hz
or something else.so how u ppl are saying dat frequencyless
dc is more dangerous.

Answer / michael pardee

AC is more dangerous, because nerves tend to be excited by
by the polarity reversals of AC and blocked by the steady
state of DC. That is the oversimplified, short answer, but
it explains why AC is hard to let go of when the current
reaches dangerous levels. I've never had trouble letting go
of DC!
I used to work with vacuum tubes in Ye Olde Days and got
across 250-300 volts DC many times, once with excellent
hand-to-hand contact. 300 volts DC hurts as much as 120
volts AC, but feels different. DC shocks are like being hit
by a board; AC shocks feel like a herd of giant deranged
ants stampeding through your body.

Answer / pady

in dc there is no 0 point in cycle of current,while in ac we
have a chance at 0 point of cycle....soo...dc dangerous

Answer / siddharth srivastava

sushmita..tu kis type ki current hai...aisi hi current ya
dangerous current.??plz reply with ur email id??wll be
waiting f u ...byeeeee

Answer / arul

Mr. Pardeep. U Need to be more aware of Electrical Shocks.
U Made a point that DC is not dangerous, If so then Why
Capacitor Banks in Power stations are being isolated
completely from the reach of Man..? My point is DC is more
Dangerous as comparred to AC. In accidental contact with
High Voltage DC source, the living body gets attached with
the strong attractive force where the Biological ionic
cells gets attracted towards it. Where as in AC, one of the
two half cycle helps the body to repel out from the AC
source. i.e the Body will be thrown out with an axtreme
force. Perhaps, this may not lead to loss of life unlike DC.

Answer / ajit

DC or AC!It is the matter of current flowing through it to
cause d shock intensity.I am working with 800Ah DC battery
set and accidentally the electrodes got short ckt by the
spanner.What is the result? spanner "melt" down
completely!In dc if u come in contact with both the
polarities it is more dangerous than ac.
