In a Headset-Chestset, a _____ only affects an individual station.

• A. Open
• B. Short
• C. Ground
• D. Fault

Answer: (A)

In a headset-chestset arrangement, each station is fed independently along the line, so stations are effectively in parallel. If the circuit at one station opens, that station simply has no current flow and becomes dead, but the rest of the stations keep working because their paths remain closed. An open is a localized failure and doesn’t disturb the others.

A short or a ground fault, on the other hand, changes how current flows on the line and can affect more than one station—potentially loading the line, causing noise, or taking the whole circuit down. A fault is too vague; it could be any issue beyond a single, isolated stop in that one station.
