Person can be electrocuted while taking a bath touches a poorly insulated light switch, why shock more danger?

These days they may well get away with it. Almost everything touching the bath water is connected via plastic and PTFE connections. Not to be relied upon, though.





If there is a current path, main reason the shock is quite often fatal is that the contact to the body is intimate. Normally, the surface of the skin resists the voltage applied and current is low. When the surface is in contact over a wide area, the current can be high and it may concentrate in life giving organs (such as the heart). Stopping the heart is almost always fatal.Person can be electrocuted while taking a bath touches a poorly insulated light switch, why shock more danger?
the magnitude of the shock is dependant on many things.the amount of voltage received will depend on how well you are making earth contact and the fact also that the water also has minerals/salts etc which improve electrical conductivity
