Question

The National Institute for Occupational Safety and Health (NIOSH) states "Under dry conditions, the resistance offered by the human body may be as high as 100,000 Ohms. Wet or broken skin may drop the body's resistance to 1,000 Ohms," adding that "high-voltage electrical energy quickly breaks down human skin, reducing the human body's resistance to 500 Ohms."

In class you learned that Amperage kills you, not Voltage, and that the lethal range of Amperage runs from about 100 to 200 mAmps (0.100 – 0.200 A). Interpret the risk of working around the battery in your car.

Explanation / Answer

sometimes wen we work with a car batteyhaving 12 V ,we get a tingling sensation due to sweat. we will never have a problem with the voltage. always the current factor plays an important role. our body will have some value of resitance and upto certain limit of current can be bearable.

house hold batteries will have lare amount of internal resistance whih may not effect human body. but the battery of a car will have small amount of inetrnal resistance which results high output current. therefore one has to be careful while working with the battery of a car.
