why one pin of plug pin is longer than other two? In some
mobile chargers one pin is made not conducting .Why?
Answer Posted / kaustuv
another reason is that....even by mistake we can't insert d
earth pin into live socket....If for instance the earth pin
comes in contact with the live wire....the metallic or
earthed part of the device is in direct contact with live
wire and we will get an electric shock if we touch the
metal body of the device.
