Question

why do we feel shock in ac current and not in dc

Answer 1

In terms of fatalities, both kill but more milliamps are required of DC current than AC current at the same voltage. ... This typically takes place at 30 mA of AC (rms, 60 Hz) or 300 – 500 mA of DC. Though both AC and DC currents and shock are lethal, more DC currentis required to have the same effect as AC current.

Answer 2

It is a wrong concept to think that DC current does not harm while AC current does.If it was so no one would have used AC but Scientist Tesla was bold enough to prove that Edison was wrong and showed the world that AC IS MORE.BUT SAFER THAT DC.
Now coming to your question, your misconception may create that no harm is caused from 1.5V-2.4V batteries but you get a shock when there is some leakage in household AC run appliances.
It is because household appliances run at 230-240 V AC.If you take some voltage from DC you'll surely get a severe shock!!!
Actually once you touch a conductor having 240V it is not possible to loosen it's grips.
While currents having the order of 1mA can be felt,you cannot feel current from 12 V battery as the body provides the resistance of 100 kilo ohms(if skin is dry) I.e. current at 12 uA. But currents having higher voltage will surely get into a shock!!
