dc

a.c is more dangerous....

DC is more dangerous, since there is no natural zero in DC 
as in AC...

Both are dangerous and it mainly depends on the amount of 
voltage and current present......but DC is very dangerous 
when compared to AC

Both are dangeruos but DC is more dagerous than AC because 
AC is alternating current & flow of sine wave & once a cyle 
is zero and maximum for take reference line, but DC is 
direct current & not fraction of time period for reference 
line and DC flow of state line,so DC is dangerous.

dc is moredangerous than ac.
based on ac sinosoidal wave, alternating current and voltage
has reaches 0 at at each half cycle which is the weak point.
On the other hand DC has straight wave.

One example is the rail way train which uses dc, because it 
has strong torque at starting compare to ac.

D.c is more dangerous as compare to A.C. 
In case of a.c current and voltge change time to time. And 
its value become two times equal to zero.
Vi=Vmsin(wt)
Vi is equal to zero after 180 and 360 degree.
