Which statement regarding electrical current is true?

The correct answer emphasizes the relationship between current, voltage, and the risk of electrocution. It is fundamentally true that electrical current can be lethal, and that both high and low voltages can result in dangerous levels of current under certain conditions.

When discussing electrical safety, it's important to note that voltage is the potential that pushes current through a conductor, while current is the actual flow of electrons. The lethality of a shock is determined not just by the voltage but by the path the current takes through the body, the resistance of the body, and the duration of exposure.

For instance, under dry conditions, the body has a relatively high resistance, meaning that a higher voltage might be needed to push a significant amount of current through the body. However, wet skin can drastically lower resistance, allowing even low voltages to produce a lethal current.

Thus, it is crucial to understand that both high and low voltages can be hazardous depending on the circumstances. Awareness of this fact is essential for anyone working with electrical equipment, particularly in biomedical settings where safety is paramount.
