Answer / kaushik (ms university)

In dc and ac ,dc is more dangerous. b'coz in dc there is
continuous voltage where is in ac there is alternating
cycle.so there is a moment at which ac voltage crosses the x
axis .so when there is any shock in our home then we had
just a shock for a moment

Answer / ankit

ac is alternate current.
Dc is direct current.
In our house 230 V ac is used. If u get
shock.. There is a chance to escape as
voltage is low and ac current crosses zero
at every half cycle...
But dc current can do much damage to u
as it does not crosses zero...constant full
dc voltage is applied to u.

Answer / lakshmi

IN DC FREQUENCY IS CONSTANT THATS WHY DC REPRESENT BY
LINE.BUT NOT IN AC,AC REPRESENT BY SINE WAVE.THIIS IS THE
MAINDIFFERENCE
DC IS MORE DANGEROUS COMPARED TO AC BECAUSE OF ABOVE
REASON.IF WE ARE GETTING SHOCK FROM AC IT WILL LEAVE AFTER
3OR 4 SEC WHY BECAUSE ITS HAVE ALTERNATING CYCLE.

Answer / nani eee

we know ac supply is alternating supply nothing but voltage
and dc is direct supply there is no alternating gives onely
constant voltage if we get shock with dc the voltage is
constantely flow in your body then your body domains on
blood cells are randomely disturbuted then you will get
shoke the domains are move in same direction then heat will
be disipeated the heat the heat causes contineously in dc
causes deat there fore dc is more dangerous then ac
