EMI in low-voltage circuits is often the result of what?

Electromagnetic Interference (EMI) in low-voltage circuits is most commonly attributed to sharing pathways with power circuits. When low-voltage data cables run alongside or within close proximity to high-voltage power lines, the electromagnetic fields generated by the power circuits can induce noise or interference in the signals of the data cables. This can lead to degradation in the performance of the low-voltage systems, causing issues such as data loss or corruption. Proper installation practices recommend physical separation of low-voltage and high-voltage cabling to minimize the risk of EMI, thus ensuring more reliable performance of both systems.

The other options, while they may relate to broader issues in cabling, do not address the specific cause of EMI in the context of low-voltage circuits as directly as the interaction between data and power circuits.
