AC is normaly 230v 50Hzs why ?

Answer Posted / shuvodeep das

The current 230v 50hzs are given to the household by keeping the safety precaution. The voltage 230v is not sufficient for causing a human death unless someone is a heart patient. And the frequency of 50hzs can vary to 60hzs as well. The current property is repulsive which cause a person to reflect his body part when he is in touch with open wire. Where in the other hand the cables which take 1000 of MVolts eleect.. are having attractive property.
