Wiring a duplex receptacle
Looking at the duplex receptacle from the front side directly on, you should see a larger blade hole (silver) on the left, smaller (brass) blade hole on the right and a U shaped ground blade on the bottom. The white wire connects under the left (silver) coloured screw, the black wire connects under the right (brass) coloured screw and the green wire under the green ground screw.

For AC connections, there is no such thing as "positive". The convention there is that the "neutral" wire is white, the ground wire is green, and the "live" or "hot" wire is ... whatever isn't white or green (usually black in a two or three wire situation, but in multiphase or industrial wiring where it's important to be able to distinguish what circuit a given wire belongs to, red, blue, and brown are also often frequently used).
For DC connections such as are used in vehicles and electronic battery powered equipment, the color conventions are that red is usually positive and black is usually negative.

The BLACK wire is the "hot" or "live", WHITE is the neutral and the BARE or GREEN wire is the safety ground wire.
Answer for countries in Europe and other world areas running a 230 volt 50 Hz supply service.
The BROWN wire is the "hot" or "live", BLUE is the neutral and the GREEN/YELLOW wire is the "earth" / "safety ground" wire.
(In the UK, if your socket outlets are wired with the old Black, Red and Green/Yellow wires (as were used until 2006) RED is the live wire and BLACK is the neutral in the socket outlet but the BROWN wire is still the "live" wire in the plug on the flexible cord to your appliance.)
If in doubt, please leave it to the professionals for your own safety!

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What else can I help you with?
In an IEC-320 plug which wire carries electrical voltage?
the hot wire carries the electrical voltage
When removing an electrical plug from its socket grasp the electrical cord?
Do not remove any electrical plug by grabbing the wire. This weakens the connection at the plug. ALWAYS grab the plug itself when removing it.
What is the purpose of the white electrical wire in a typical household wiring system?
The purpose of the white electrical wire in a typical household wiring system is to carry the current back to the electrical panel or source after it has been used by the device or appliance.
Can you soft wire an electric water heater and plug it into a household outlet?
If it does not come with a plug on it, no. If it is made for direct wire, then 99.9% chance is that it is a 240 volt unit. If you plug it into a 120 volt outlet your water will barely get warm.
What do you plug a block heater into?
plug a block heater plug into any household 120 electrical outlet just like plugging in a heater in your house
What is a Black wire in a household circuit?
Answer for USA, Canada and countries using similar 60Hz household electrical servicesBlack insulated wire is used for a "Hot" (or "Live") wire. Answer for European and other countries using similar 50Hz household electrical services In old wiring, as was used for household electrical circuits installed in the UK prior to 2006, the "Neutral" would have been a black insulated wire. Black insulated wiring is not used for that purpose today. For more information see the answers to the Related Questions shown below.
Is the wide prong on an electrical plug connected to the black wire?
No, the wide prong is neutral it is the white wire. The narrow prong is hot it is the black wire. The round prong (in a 3 wire plug) is safety ground it is the green wire.
What is the recommended gauge for electrical wire to use in a residential setting, specifically when considering the use of 18 gauge electrical wire?
The recommended gauge for electrical wire in a residential setting is typically 14 or 12 gauge wire. 18 gauge wire is generally not recommended for household use as it may not be able to handle the electrical load safely.
What is a plug on neutral and how does it differ from traditional electrical wiring systems?
A plug on neutral is an electrical wiring system where the electrical outlets have a neutral connection built into them, eliminating the need for a separate neutral wire in the electrical circuit. This differs from traditional electrical wiring systems where each outlet requires a separate neutral wire connection.
How does a distributor work?
The distributor takes the electrical output from the coil and sends it to the spark plug. The rotor is the device that transfers the electricity from the coil wire to the spark plug wire.
What is 14 gauge wire used for in electrical applications?
14 gauge wire is commonly used for general household electrical wiring, such as lighting circuits and outlets. It is suitable for carrying moderate amounts of electrical current safely.
How do you properly wire a 3 prong plug for electrical appliances?
To properly wire a 3 prong plug for electrical appliances, you need to connect the green wire to the ground terminal, the white wire to the neutral terminal, and the black wire to the hot terminal. Make sure to follow the manufacturer's instructions and use proper safety precautions when working with electricity.
