ＪＵＳＴ IN CASE

This is a text message circulated on the Internet 

A few days ago, a person at home charging his handphone. At this point the phone rang. He did not unplug the charger and answered directly.After a few seconds, power flow through the phone. The young man were shocked to the ground. 

His parents burst into the room and found that he had lost consciousness, weak heartbeat and fingers burned.He was immediately taken to the hospital. But was declared dead on arrival. 

Mobile phones are very useful for modern inventions. However, we must be vigilant. Mobile phones can also be deadly weapons. Do not use your phone when it is connected to a power source. We all have this knowledge, but still do so as to answer the phone. Why??????
 
According to the Internet as well as journalists, we are sure there was such an incident happened.But we are not sure whether it is really risky to answer the call when it is charging. That incident happened just because the phone is on charging? Who knows !!!
 
Generally speaking mobile phone charger is less than twelve volts. So despite the phone or charger leakage, the chance of electrocution is almost zero. But despite the small probability (Almost equal to zero, but not equal to zero), we better avoid talking on the phone while charging. ＪＵＳＴ IN CASE !!!
