Which statement about the standard voltage for lighting and scene power is correct?
Correct Answer:
110-Volt AC
Explanation:
The key idea is that lighting and scene power on most productions are supplied as alternating current at about 110 volts. This AC supply is what dimmers and standard lighting gear are designed to work with, allowing smooth brightness control. DC power is not the usual source for mains lighting, and 220 volts is typical in regions outside the US. So 110-Volt AC best matches the standard you’re likely studying.
