Which of the following statements is true regarding electrical safety in proximity to lines?

The statement that induced voltage risk increases with proximity is accurate because as a person or an object gets closer to electrical lines, there is an increased likelihood of experiencing induced voltage. Electrical lines operate with alternating current (AC), which generates an electromagnetic field around them. This electromagnetic field can induce voltage in conductive materials nearby, such as metal structures or even the human body.

The closer one is to the electrical lines, the stronger the electromagnetic field's influence, thereby elevating the risk of electric shock or other safety hazards. This understanding is crucial for maintaining safety protocols when working near high voltage lines, as proper distance and safety measures must be followed to reduce risk.

The other statements do not accurately reflect electrical safety principles. For example, the notion that all electrical lines are completely safe is misleading; safety can never be assumed without adherence to regulatory practices and safe working distances. More grounds decreasing safety risks is incorrect because while grounding is vital for safety, having inadequate grounding can lead to increased risk rather than decreased. Finally, the idea that electrical circuits do not interact is not valid; electrical circuits can interact, and this interaction can have significant effects on safety and performance.
