According to electrical safety, what are the three factors that determine the damage caused by current through the body?

The correct answer identifies the three critical factors in determining the damage caused by electric current passing through the human body: duration, amount, and path.

Duration refers to the length of time the body is exposed to the electric current. Longer exposure increases the likelihood of serious injuries or fatalities, as the body may not have enough time to react or a way to break the circuit.

Amount signifies the magnitude of the electrical current that passes through the body. Even a small amount of current can be dangerous under certain conditions, but higher currents are generally more hazardous and can lead to severe trauma or death.

Path is related to the route the electric current takes through the body. Different pathways can result in varying degrees of injury; for example, a current passing through vital organs such as the heart can be much more damaging than one that travels through less critical tissue.

In contrast, the other options include terms that do not accurately capture the three decisive factors contributing to electrical injury. For example, “current, voltage, resistance” encompasses principles of electrical theory but does not specifically pertain to how current affects the body in terms of safety. Thus, the chosen answer accurately reflects the elements that linemen and electricians need to understand for safety when working with electricity.
