What is the definition of wraith?
A wraith is a ghost, spirit, spectre, phantom, or shade, often of dark nature. The word wraith is used to describe evil spirits in many different types of literature and media. An example might be the Ring Wraiths, or the Nazgûl, from the Lord of the Rings Trilogy. These are wraiths as they are manelovent and evil. I hope my definition of "wraith" was helpful and a fair equal to your other sources.

What is a circuit breaker in tax preparation?
what do you mean?
a circuit breaker is a device usually used in domestic fuseboxes and appliances, that when a circuit current (amount of amps) is higher than the current set to the breaker as the trip current, the breaker will trip, preventing the wire from overheating and possibly shorting out (see internet) which might cause bigger problems.
the breaker may also trip if a short occurs.
but tax preparation...
i'm afraid i am not even familliar with the term : /
i have a feeling though that in "tax preparation" it might be a metaphorical term.
i hope the first part helps though!
if you have any more questions...
just ask! :D
Where does the voltage of 347 volts come from?
It's one phase of a 600V system. Or so I've heard the electrician say. I'm a plumber, don't ask me.
Is it possible to change the frequency in an electrical substation?
yes, it is possible to change the frequency in substations. frequency changer is a motor-generator set that changes power of an alternating current system from one frequency to one or more different frequencies, with or without a change in the number of phases, or in voltage. Sometimes a converter is used to accomplish this.
Can you run a 220 50hz pump on 220v 60hz power supply?
In general the answer has to be: "Not if it has been designed and wired to run only on the 50 Hz mains frequency system that is used in Europe and elsewhere."
The mains frequency in Europe and other 230 Volt areas is 50 Hz (Cycles per second) compared to 60 Hz in US, Canada and other 120/240 Volt areas. Some 50 Hz appliances may work fine but others with simple motors will run too fast on the higher frequency of 60 Hz.
However the most important difference is how the Neutral wire is connected:
In a 240 Volts 50 Hz appliance has 3 wires altogether, a "Ground" conductor, one single 240 volt "live" or "hot" wire and a Neutral wire connected as a return to the single "hot".
An appliance designed to run on 240 Volt 60 Hz supply has 4 wires altogether: a safety "Ground" conductor and 3 further wires, namely a Neutral wired as a "central" common return conductor and two 120 Volt 60 Hz live "hot legs" which run in opposing phase to one another. When one hot leg is "+" (120 Volts positive) the other leg is "-" (120 Volts negative).
So there is a 240 Volt voltage difference between the "Neutral" and the "Hot" conductor in the 50 Hz system and only a 120 Volt voltage difference between the "Neutral" and the "Hot"conductors in the 60 Hz system. In the main breaker box, at the point where the "Neutral" gets connected to the "Ground", this difference will cause serious problems! That is why an appliance designed to be connected onto the 50 Hz system cannot be used safely on the 60 Hz system without first having proper technical modification work done.
A licensed electrician or electrical engineer would be able to consider whether or not a particular large appliance, that was manufactured to work on 50 Hz-only, could be modified to run safely at the higher 60 Hz frequency. However it won't usually be worth the expense of doing the work because it would be more cost-effective to buy (new or secondhand) an equivalent large appliance designed to work on 60 Hz.
Further information which may be useful to mention here but is not part of the answer to this question:
Some small "double-insulated" 50 Hz appliances, such as electric shavers, etc., have been designed to run safely on different supply voltages and frequencies. If that is so, it would be stated on their rating plates.
In many cases, where the power needed is low, such as (say) less than 30 Watts, a cheap and simple "International Travel Socket Adapter" is all that is needed to make such an appliance plug-in and work. Many international airports have shops selling such adapters.

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.

Concealed wiring is wiring that can not be seen. A good example of this is house wiring that is located behind the wall board. The word concealed gets mentioned in the electrical code. It states, that any concealed wiring cannot be covered until the electrical inspector or one of his representatives checks to make sure that the installation is safe to cover.
Can MgSO4 conduct electricity?
When molten or dissolved in water it can but in its standard, solid state it cannot.
What size wire would you use to wire a motor that draws 16 amps from a circuit?
AWG Wire Ampacity
Gage (Amperes)
16 10 A
14 15 A
12 20 A
10 30 A
8 45 A
6 65 A
4 85 A
2 115 A
1 130 A
0 150 A
So if anything its probably 12-14 gauge wire

Is a ground fault required in a basement?
Yes, If it is unfinished. Reference National Electrical code NFPA 70 for additional details.
What is the current path in an overcurrent fault condition?
The current path in an over current fault is the path of least resistance. Older electrical systems used to use the neutral wire for this purpose. It was found that on some occasions this was not the path of least resistance. Hence the installation of a ground wire being installed in cable sets. This innovation caused the whole grounding section in electrical code books to be rewritten. Now a specific ground wire is used to bring the fault current back to the distribution panel to trip the breaker and open the faulted circuit.
Meaning of 60watt's in 60watt's bulb?
60 Watts is the amount of electrical power the bulb uses when it is switched on.
Is there a machine that types what you say?
well in terms of things you say i dont think so but you can buy things that are voice command and there not so much
What is a mcb and what is it used for?
mcb is master circuit breaker. it is used in the circuit for the protection of equipments from over voltage.
Is 120vac the same as 120vrms?
No. RMS is the the true heating ability of A.C. RMS means root mean square. That is the square root of two divided by 2 equals 0.707. Multiply the A.C. times 0.707 equals RMS.
Path made for an electric current?
A path made for an electric current is classified as a conductor and can come in the form of many shapes and sizes.
11.6 amps equals how many watts?
11.6 amps equals zero watts. Watts is the product of amps times volts. W = A x V. As you can see voltage is needed to obtain the wattage of a device.
How does cell phone reception depend on the time of day or location?
The time of day doesn't matter but the distance from the nearest cellphone tower does. If the signal is too weak the phone won't work.
Plugged in one outlet heater and 7 outlets aren't working and no tripped fuses?
Most receptacles are wired in parallel to separate circuits in household wiring. trace the circuit back until you find a 'live' plug. From that point to the next outlet, there could be a loose, bad or unhooked wire. before you go removing receptacles, be sure to pull the breaker (shut the breaker off). All wire connections should be tight.
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

In what type of circuit does electricity travel when it does work?
Electricity travels in a closed circuit when it does work.
What are the Computer wires and cables and circuits called?
The wires and cables in a computer are often, collectively called "innards" or "guts."
Why do electrical wires have plastic covering?
Electrical wires have plastic covering as when electric current flows through the copper wires and mistake we hold it so we may get an electric shock.
