• Electrical current produces ohmic heating.
• Rate at which energy is delivered (power) in ohmic heating increases as voltage goes up and as resistance goes down.
• The nervous system uses electrical signals to activate muscles, including the heart.
• Electrocution typically occurs due to a fatal disruption of the body’s nervous system caused by a large current.
• Electric current can also restart the heart’s pacemaker circuit (defibrillation).
