A current of as little as 0. However, the current involved in an electric shock is determined by the voltage and the resistance of the circuit. The human body has an inherent high resistance to electric current, which means without sufficient voltage a dangerous amount of current cannot flow through the body and cause injury or death. Death is likely. Death is probable. Spread The Science!

Are these values for DC or AC as I know dependant on the supply type, not just the voltage levels affects the body in different ways Reply. Best regards Reply. Rishabh Venketesh said: July 31, at pm.

The low resistance of wet skin allows current to pass into the body more easily and give a greater shock. When more force is applied to the contact point or when the contact area is larger, the resistance is lower, causing stronger shocks.
Power drills use 30 times as much current as what will kill. The path of the electrical current through the body affects the severity of the shock.
Currents through the heart or nervous system are most dangerous. If you contact a live wire with your head, your nervous system will be damaged. Contacting a live electrical part with one hand—while you are grounded at the other side of your body—will cause electrical current to pass across your chest, possibly injuring your heart and lungs. The greater the current, the greater the shock! Severity of shock depends on voltage, amperage, and resistance. Currents across the chest are very dangerous.
The customer then left the house and returned 90 minutes later. She noticed the service truck was still in the driveway. After 2 more hours, the customer entered the crawl space with a flashlight to look for the technician but could not see him. She then called the owner of the company, who came to the house.
He searched the crawl space and found the technician on his stomach, leaning on his elbows in front of the furnace. The assistant county coroner was called and pronounced the technician dead at the scene. The victim had electrical burns on his scalp and right elbow. After the incident, an electrician inspected the site.
The owner of the company stated that the victim was a very thorough worker. Perhaps the victim performed more maintenance on the furnace than previous technicians, exposing himself to the electrical hazard.
