The injury from an electrical shock depends on
the type of current
how the current traveled through the body
the intensity of the voltage
The harm or injury from an electrical shock depends on whether the current is low or high, the intensity of the voltage (high or low), how the current travelled through the body i.e. whether the person was wearing rubber chappals or had any kind of insulation during the flow of current through the body, the person's overall health and how quickly the person is treated.
