Question
Which of the following can cause interference in a cable? Choose three.
- Remote controls
- Electric outlets
- Electric lights
- Motors
Solution
Interference in cables can be caused by various external factors. In this case, the three options that can cause significant interference are:
-
Electric Motors - These can generate electromagnetic interference (EMI) due to the electric current they use and switching operations, affecting the signals in cables.
-
Electric Outlets - They may also introduce noise or interference in electrical lines, especially if there are issues with grounding or if they are overloaded, leading to voltage fluctuations.
-
Electric Lights - Certain types of lighting, especially fluorescent lights or those with dimmers, can produce electromagnetic radiation that interferes with cable signals.
Remote controls typically do not generate the kind of electromagnetic interference that affects cables significantly compared to the other options listed.
Thus, the three choices that can cause interference are Electric Motors, Electric Outlets, and Electric Lights.
