the shock experienced when one touches a live wire is attributed to several factors.......
firstly,the 220v value is only the rms value,the actual value is close to about 311v.....
any live wire has rapidly fluctuating current that moves from -311v to +311v in 1/60th of a second......the frequency is quite high.....
then,ac current is able to flow through the body surface only........instead of moving through the bulk......
then again,u will gt a shock only whn u r standing on d ground and touching d live wire,as d ground is an effective absorber of charge and is able to create a sufficiently high potential gradient.....
