Question

if the the A.C. current is changes its direction continuously So why we get shock only on touching one wire of power supply of our houses, why we don't get shock on touching other wire of power supply ???

Answer 1

Here is the simplified circuit of the system to understand. If neutral is earthed it will be at 0 potential (0 potential reference) always. The section of wire marked with B is maintained at 0 potential till the switch is open. So, If you touch this part of wire you won't feel any shock if switch is open.
