True or False: A tiny fraction of an ampere can be fatal.

A tiny fraction of an ampere can indeed be fatal, which is why the answer is true. The human body can be very sensitive to electrical currents. As little as 0.1 to 0.2 amperes (100 to 200 milliamperes) passing through the heart can result in fatal arrhythmias or lead to cardiac arrest. Factors such as the path the current takes through the body, the duration of exposure, and the individual’s physical condition can all influence the risk, but even small amounts of current can pose serious dangers.

Understanding the implications of electric shock is crucial in promoting safety practices and awareness, especially in situations where individuals may be working with or around electricity. Safety measures such as using protective gear, ensuring proper grounding of electrical installations, and adhering to electrical codes are vital in reducing the risks associated with electrical exposure.
