What is "stray voltage"?

Stray voltage refers to the phenomenon where voltage is found on conductive surfaces that is not the result of intentional electrical circuits. This can occur due to various factors, such as unintentional grounding issues, leakage currents, or the presence of electromagnetic fields from nearby energized equipment. Stray voltage can be particularly concerning in environments where electrical safety is critical, as it may lead to shocks or unsafe situations for individuals who come into contact with these conductive surfaces.

In contrast to the correct answer, the other options focus on specific conditions or intentional systems. The presence of voltage from intentional electrical circuits, voltage fluctuations during power surges, or voltage generated by solar panels cannot be classified as stray voltage, since they stem from direct and expected electrical sources rather than unintended voltages on external surfaces. Understanding the concept of stray voltage is vital for ensuring safety in environments that utilize electrical devices, especially in theaters, auditoriums, and other entertainment venues.
