You can have only one current carrying conductor in a conduit, but that conduit must have a slot to relieve the eddy currents that will be created by the transformer effect created by the conductor. It is better to run the neutral or opposite conductor along with the hot conductor together in the same conduit, or through the same penetration, so as to minimize this effect.
What else can I help you with?
Do all current carrying conductors emit electromagnetic waves?
No. Only those carrying AC. Those carrying DC have a constant magnetic field around them and emit no waves.
Does electric current flow only on the surface of the copper conductor?
The AC current tend to flow on the surface of the conductor. The higher the frequency, the thinner the skin. This is known as the skin effect. So DC current flow throught the entire conductor but when the signal varies (AC) there is the formation of eddy current in the conductor itself and that pushes the electrons at the surface of the conductor. You can get more information on the skin effect and skin depth on wikipedia : http://en.wikipedia.org/wiki/Skin_effect http://en.wikipedia.org/wiki/Skin_depth
How much current will flow in service wire?
In a service drop conductor the only limiting factor is the first over current device down stream from the service.
Is metal the only conductor?
No, metal is not the only conductor. Other materials like water, graphite, and some types of plastics can also conduct electricity to a certain extent. Conductors allow the flow of electric current due to their free-flowing electrons.
Is resistivity of conductor independent of charge?
Yes, resistivity, which is a material property, is independent of the amount of charge. Resistivity is determined by the material itself, while the amount of charge only affects the flow of current through the conductor.
What is the difference between one current carrying conductor in a conduit and a hot and switch leg in a conduit?
In the first part of the question there will be only one wire in the conduit, in the second part of the question there will be two wires in the conduit.
Can an overhead conductor carry more current on a cold day as compared to a hot day?
The only limit on how much current the conductor can carry, regardless ofthe weather, is the amount of current that causes the conductor to melt.The current in such a conductor depends on the voltage between its ends,and on the resistance of the conductor. The resistance of the conductor issomewhat less when it's cold, so a given voltage would result in more current.
A coil of wire with a current is called a?
Current can be induced in a conductor by passing said conductor through a magnetic field.AnswerThe word you are looking for is 'induced', not'inducted'. Current is not induced into a conductor; it's voltage that's induced. Current will only result if the conductor forms a closed loop or is connected to some type of load.
Can ground conductor use as a neutral conductor in a house wiring?
No. Absolutely not. The ground conductor is not rated to carry constant current flow. It is only rate to carry fault current flow.
If a fuse becomes hot under normal load a probable cause is?
A fuse is nothing more than a conductor [wire] that is smaller than the conductor wire in circuit which the fuse is designed and intended to protect. The amount of current [measured in Ampheres (Amps)] creates some "resistance heating" in any conductor. The greater the current in relation to the size [and current carrying capacity] of the wire, the greater the heat generated. A fuse that runs warm or hot only indicates that it is carrying a lot of current, possibly near it's limit. When the current limit is reached, the fine wire in the fuse will melt [fuse], opening, or breaking, the circuit thus stopping the flow of current and protecting the conductor wire.
Why do Concentric circles arrange around a current carrying conductor only if the cardbord is tapped gently?
The magnetic forces that cause the iron filings to align to the magnetic field are very weak and have trouble overcoming the forces of friction. When you tap the cardboard the filing jump up a bit and while they are in the air they are able to then rotate.
How do you mesure 3A current capacity?
Current Capacity of a conductor depends on may things, and not only its size and material. Also important are the conditions in which it will be used, the allowable temperature increase and acceptable voltage drop. Measuring the current carrying capacity would involve measuring all those variables under load.
When a conductor is moved in a magnetic field a voltage will be induced on the conductor. However current won't flow through the conductor unless the conductor is?
moving
What is the name for a material which lets electricity flow through it easily?
A material that allows electricity to flow easily is called a conductor. Conductors have low resistance to the flow of electrical current, making them suitable for carrying electricity. Common examples include metals like copper and aluminum.
What would one use a clamp on meter for?
A clamp meter measures the vector sum of the currents flowing in all the conductors passing through the probe, which depends on the phase relationship of the currents. Only one conductor is normally passed through the probe. In particular if the clamp is closed around a two-conductor cable carrying power to equipment, the same current flows down one conductor and up the other; the meter correctly reads a net current of zero.
Current-carrying of a machine?
Confucious say, an answer may only be found where a question exists.
What is the Acceptable current in ground cable?
A ground is not expected to carry any current. It's only there in case of a fault condition. If you have a current reading through a ground wire there is a fault that needs to be corrected. Many times a lazy electrician who couldn't find a broken neutral connected a receptacle or light fixture to ground to make it work. This is not a proper use of the grounding system, and it is dangerous and should be corrected if encountered. The grounding conductor should have at least the same ampacity of the largest phase conductor connected to the circuits it protects. That way it is capable of carrying the full current of the largest conductor in case of a fault.
