Our electrical suppply in our home is alternating current(a.c) 
right? Since a.c current does not a definite charge on any of the 
two wire, why is it that in our home only the live wire carry 
electricity while the neutral wire is neutral? If our power 
supply is a.c, the live and neutral wire can be 'live' since a.c 
current is alternating. The live wire can be both positive and 
negative charge and so does the neutral wire. Why is it that only 
the live wire is charged while the neutral wire is neutral?
