NABCEP PV Installation Professional Practice Exam

Question: 1 / 400

What are the three main factors that determine the severity of electrical shock?

The type of electrical source, the path of current flow, and the equipment used

The amount of current, the path of current flow, and the duration of exposure

The selection of the factors that include the amount of current, the path of current flow, and the duration of exposure accurately reflects the critical elements influencing the severity of electrical shock.

The amount of current is fundamental since it directly affects how much energy enters the body; even small currents can be dangerous if they flow through vital areas, such as the heart. The path of current flow is equally important because certain pathways, like those through the heart or brain, can lead to more severe outcomes than others. Lastly, the duration of exposure plays a significant role since longer exposures can increase the likelihood of injury.

Understanding these three factors is essential for assessing the risks associated with electrical work and implementing effective safety measures to mitigate these risks.
