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

1. They cannot be powered by AC sources

2. They consume less power

3. They can pass current to other devices

4. They operate at lower temperatures

The correct answer is: They can pass current to other devices

The statement regarding line extenders powered by the network that is accurate asserts they can pass current to other devices. This capability is integral to their function, enabling them to amplify and extend the communication signal while simultaneously providing power. This is particularly relevant in network configurations where multiple devices need to be powered and connected over a distance. By allowing the current to pass through, these extenders ensure that downstream devices receive the necessary power and data signals to operate effectively. Considering the other statements, the assertion that line extenders cannot be powered by AC sources is misleading, as many can indeed operate with AC input. The claim about consuming less power is not universally true as it depends on the specific design and application of the extender. Finally, the statement regarding operating at lower temperatures may apply to only certain models but does not hold as a general rule for all line extenders powered by the network. Therefore, the ability to pass current to other devices is the key defining characteristic that validates the given answer.
