Final answer:
Electrocution is the term used to describe the physiological reaction or injury caused by an external electric current passing through the body. Safety precautions, such as wearing insulated shoes and working with one hand, are used to minimize the risk of electrocution.
Step-by-step explanation:
Electrocution is the term used to describe the physiological reaction or injury caused by an external electric current passing through the body. It can range in severity from a painful shock to a heart-stopping lethal shock. When a current with a magnitude above 300 mA passes through the heart, death may occur. Safety precautions, such as wearing insulated shoes and working with one hand, are used to minimize the risk of electrocution.
