Which wire is the wire?
The white wire is the “neutral” wire, which takes any unused electricity and current and sends them back to the breaker panel. The plain (or it can sometimes be green) wire is the “ground” wire, which will take electricity back to the breaker panel, then outside to a rod that’s buried in the ground.
What are the four types of wire?
Different Types of Electrical Wires and Cables
- Communications Cable. Coaxial Cable.
- Direct-Buried Cable (DBC)
- Non-Metallic Sheathed Cable (NM, NM-B)
- Metallic Sheathed Cable (Armored Cable, AC or BX, MC) Armored Cable (AC)
- Multi-Conductor or Multicore Cable:
- Paired Cable.
- Portable or Extension Cord.
- Ribbon Cable.
What is the common wire in electrical?
White. The “common” is the “neutral” or “ground” wire, depending on the type of circuit. In normal US residential wiring, you’ll have a black “hot” wire, a white “neutral” or “common” wire, and a green or bare “ground” wire.
Is red wire hot or neutral?
Red wires are usually used as secondary hot wires. Red wires are also hot and should be clearly marked to avoid the dangers of electrocution. Red wires are commonly used when installing ceiling fans, where the light switch maybe.
How is a Wire sized in Electrical Engineering?
Wire is sized by American Wire Gauge system. Your installation of conductors will depend on a few factors like gauge of the wire, wire capacity, etc. For wires, smaller the wire gauge larger the ampacity or capacity of the wire to handle current.
What are blue and yellow wires used for?
Blue and Yellow wire: These wires are also used to carry power but are not wiring the outlets for common plug-in electrical devices. They are used for the live wire pulled through the conduct. You will see yellow wire in the fan, structure lights, and switched outlets.
How to ask questions in an electrical engineering interview?
20 Electrical Engineering Interview Questions & Answers 1 What happens when two positively charged material is placed together?

What are the three types of electrical cables?
Cables are categorized into three forms according to its thermal capacity 6) Mention what are the different colors on wires indicates? Black wire: This wire is used for power supply in all circuits. Any circuits with this color is considered hot or live. It is never used for a neutral or ground wire.
