Question

Some wires, especially signal wires and communication wires, are shielded, which helps to prevent electromagnetic interference, also referred to as "____."

Answer 1

Cable shielding is done on some wires like signal wires and communication wires to prevent electromagnetic interference (EMI), also known as noise.

Step-by-step explanation:

• In regions where strong electromagnetic interference is present, like inside some vehicles the wires are subjected to unwanted electromagnetic induction.
• This interference is known as Electrical noise or EMI noise. Shielding of wires is done to prevent this noise in some vehicles. The shielded wire then needs to be grounded properly.

• Three types of shields are popular: Mylar tape, drain line and twisted pair.
