True or False: Voltage can cause fatal injuries to a person.

1. True

2. False

3. Only in high amounts

4. Only under wet conditions

The correct answer is: False

The assertion that voltage can cause fatal injuries to a person is indeed true. It is important to understand that it is not just the voltage itself, but also the current that flows through the body that poses the actual risk of injury or fatality in an electrical shock scenario. The human body can respond differently based on several factors, including resistance, path of current, duration of exposure, and environmental conditions. While lower voltages may be less likely to cause severe harm, they can still be dangerous, particularly in specific situations where conditions change, like when a person is wet or when the electrical current takes a path that affects vital bodily functions. High voltage increases the risk of significant injury or death, but it is a misconception to claim that only high amounts of voltage or specific conditions can lead to fatal injuries. The reality is that any voltage sufficient to push a current through the body can potentially lead to serious harm, depending on the circumstances. In summary, safety around electricity should always be a priority, and it's vital to treat all electrical sources with caution, as even seemingly lower voltages can present serious risks under certain conditions.
