What statement is true regarding line extenders powered by the network?

Line extenders powered by the network are designed to enhance the reach of network connections while drawing power directly from the network itself. The correct statement regarding this functionality is that they can pass current to other devices. In a typical setup, line extenders can not only extend the network signal but also supply power to devices that require it, thereby reducing the need for additional power sources.

This ability to pass current can be particularly advantageous in installations where multiple devices need to be powered without a significant increase in the complexity of the wiring or power management. Consequently, line extenders play an essential role in maintaining efficient operation in a networked environment.

The other options do not accurately reflect the capabilities of line extenders. They do not typically consume more power than standard 120 VAC sources; their design aims to be energy efficient. While some line extenders may incorporate features like automatic voltage regulation, it's not a universal characteristic of all line extenders. Finally, line extenders operate using network power, so they do not require external batteries, as their primary function is to rely on the network's infrastructure.
