Which of the following describes the types of street lighting?

The correct choice appropriately identifies the ways in which street lighting can be categorized based on how lights are arranged and utilized. Multiple and series refer to two different configurations of light fixtures used in street lighting systems.

In a multiple configuration, several lights are connected to a single power supply, allowing for even and widespread illumination across a larger area, typical in urban settings where comprehensive lighting is needed for safety and visibility.

In contrast, a series configuration involves connecting lights one after another. While this can be effective in certain applications, it may lead to potential issues: if one light fails, it could cause all subsequent lights to go dark, affecting overall visibility.

This distinction is critical for understanding how different lighting configurations impact street safety, energy efficiency, and maintenance considerations. Knowledge of these types helps linemen and engineers design effective street lighting systems suitable for various environments and usage scenarios.
