Q:

What is the purpose of a neutral wire?

A:

The neutral wire in electronics is the wire in which electricity returns from the hot wire. It is also connected to the ground wire.

In a three-prong plug, the neutral wire is connected through the right-handed prong, when one is looking at the plug with the ground prong on the bottom. The neutral prong is the wider of the two plugs.

The ground wire is also connected to the ground to prevent short circuits. However, the neutral wire's purpose is to be part of the live path for electricity, rather than to act as a safety guard if something goes wrong. Sometimes, these two wires are mixed up, as the neutral wire is commonly referred to as the "grounded" wire.

  • Q:

    How can speaker wire polarity be identified?

    A:

    Speaker wire polarity can be identified by connecting the wires from the speaker to a 9-volt battery and seeing what speaker goes out and in. The speaker that goes out first and then back in is the one that will have the proper polarity.

  • Q:

    What color speaker wire is positive?

    A:

    In dealing with speaker wires, the positive speaker wire will be silver in color. This is only visible if the insulation is clear or see-through so that color can be distinguished. The negative wire will usually be copper in color for this same instance.

    What is the purpose of a ferrite core?

    A:

    A ferrite core is a kind of magnetic core made of ferrite and on which the windings of electric transformers and other wound components including inductors are formed. It is used to prevent eddy currents because of its properties of high magnetic permeability and low electrical conductivity. Ferrite cores are ceramic magnetic bodies that consist of soft ferrites formed into various shapes.
