Of course. Cellphones, flashlights, car-starters, trolling motors, mp3 players,
portable radios, and hand-held GPS receivers work fine without plugging into
an outlet. They are powered by chemical cells popularly known as "batteries".
No, an outlet is only a distribution point. A source of electrical energy would be the generation station, wind generator, photovoltaic cells (solar energy panels) or other devices that actually produce electrical energy by changing energy from one type (chemical, solar...) to another.
To dedicate a wall outlet means to reserve it for a specific purpose or appliance. This can be done by labeling the outlet or installing a dedicated circuit for that outlet to ensure it has its own power source separate from other outlets in the room. It is important to follow electrical safety guidelines when making any changes to your electrical systems.
One is AC and the other is DC. AC- alternating current is used in electrical outlets DC- direct current is used in batteries. An electrical outlet in your house would have 120 volts (the ones you use most, your tv, lights, radio are plugged into) or 240 volts (the ones your stove and dryer plug into). A battery voltage varies widely: AA & AAA batteries have 1.5 volts, a 9 volt battery has 9 volts, your car battery has 12 volts.
If the electrician that did the wiring was saving wire (preferable) the outlet closet to the fuse panel is the first one and the others downstream are further away. There is no absolute way to tell other than disconnecting one and see which others (downstream) are dead.
The definition of an outlet in Article 100 of the National Electrical Code book (US) is: "Outlet. A point on the wiring system at which current is taken to supply utilization equipment." You can have a receptacle outlet, lighting outlet, or some other hardwired equipment outlet. <<>> The definition of an outlet in Section 0 (Object, Scope and Definitions) of the Canadian Electrical Code book is: "Outlet. A point in the wiring installation at which current is taken to supply utilization equipment."

In an outlet, electrical energy is transformed into other forms of energy such as light in a bulb or heat in a heater. The outlet allows the flow of electrons to power devices that convert electrical energy into the desired form of energy for their operation.
Current is created when electrical charges move through a wire or other conductor. It can be produced by rotating magnetic fields (as in a generator) or by connecting a source of higher electrical potential (charge) to one of lower electrical potential, which can cause the movement of charges from one point to another.
No, the common wire is not the hot wire in electrical wiring. The common wire, also known as the neutral wire, carries the current back to the power source and completes the circuit. The hot wire, on the other hand, carries the current from the power source to the device being powered.
In the United States, if the outlet is polarized (one slot is larger than the other), the smaller slot is the positive, or hot, assuming it is wired correctly.Another PerspectiveThe above answer is correct in that there is a "hot" and a "neutral", but technically, if you are asking about true polarity, there is no positive and no negative in a housing or commercial outlet. Utility power service is referred to as "alternating current", meaning that the true polarity of an outlet reverses 60 times per second, with one side temporarily being positive and the other negative.If you are trying to use "direct current", you will need to use some kind of diode or rectifier to change the alternating current to direct current.
Basically, one option - for providing energy to a circuit - is a cell or battery; the other option is to connect the circuit to an electrical outlet. With a cell, the current will be DC; with an electrical outlet, it will be AC (alternating current, that is, the direction of the current changes several times per second). You should also keep in mind the voltage - household current has a fairly high voltage (110 or 220 volts), compared to a cell (typically around 1.5 volts) or even a car battery (usually 12 volts).
Yes, and electrical current is the flow of electrons OR any other charged particle.
A TV set is usually plugged into the wall outlet, so it gets the electricity the same way that any electrical device in your home does. The source of the the electrical energy can be coal plants, nuclear power plants, wind farms, solar energy, etc.; but it is usually some mix of these and other sources.
