Question 14 options: The energy delivered during electrocution is proportional to the amount of current. The number of protons passing through the body from electrocution is dangerous. The resistive heating that occurs from electrocution is proportional to the amount of current. The large current absorbs a lot of heat from the body as it passes through tissues.
