Answer Posted / 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.
