What is a conductor made from?
depends on what you are conducting but generally a metal is a universal conductor. if it conducts electricity well then it will conduct heat well. some metals are better than others and you can figure this out by resistance values of the type of metal. more resistance makes it a less efficient conductor. insulators have very high resistance.
If we increase the current then what about the power factor?
The power factor depends on the phase angle between the voltage and current on a conductor. The amplitude of the current has no effect on it.
Application of electrical circuit analogies in magnetic circuit?
Magnetic circuit follows equation (4) that is Ni = (Ф) ( l / μA) or m.m.f(magneto motive force) = (Flux) (reluctance).Electric circuit follows ohm's law that is E = I.R or e.m.f(electro motive force) = (current) (Resistance)From above point m.m.f in magnetic circuit is like as e.m.f in electrical circuit.Flux in magnetic circuit is similar as current in electrical circuit.Reluctance in magnetic circuit, S = ( l / μA) is similar to resistance R = (ρl/A) in electric circuit.Permeance (= 1/reluctance) in magnetic circuit is equivalent to conductance (=1/resistance) in electric circuit.In magnetic circuit flux establishes but not flow like as current in magnetic circuit.In magnetic circuit energy needed only to establish the flux but no consistent energy need to maintain it whereas in electric circuit continuous energy needed to flow of current.Resistance of an electric circuit is constant (for same temperature) and is independent of current but reluctance of magnetic circuit is not constant because it depends on μ (=B/H) which is not constant and depends on B/H.
If you were to mechanically rotate the armature in an electric motor what would happen?
You said "armature" so it is a dc motor. Hence if the field is permanent magnet type then a voltage appears at the armature terminals nd its magnitude depends on the speed nd magnetic field strength. If it's field coils, then they must be seperately excited (if it don't possess residual). By changing the field strength you can vary the voltage produced at armature terminals.
Is stacking of cables in cable tray permitted?
See NEC Article 392. It depends on the voltage, conductor size and the type of cable tray selected.
20 The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the and the of the conductor?
speed and lenght
The magnitude of the voltage induced in a conductor moving through a stationary magnet field depends on the?
The speed of the conductor through the magnetic field, which translates into the number of magnetic lines of force the conductor can cut per unit time, will determine the magnitude of the voltage induced in the conductor. As an additional factor, if a longer piece of wire can be moved through the magnetic field, it will induce more voltage as well. The more speed we can put on the conductor, and the more of the conductor we can move through the magnetic field, the more voltage we can induce in the conductor.
Why and when does a current carrying conductor kept in a magnetic field experiences a force list factor on which the direction of this force depend State the rule which may be used to determine the di?
Current carrying conductor will have magnetic lines around it. So when it is kept perpendicular to the magnetic field then the force would be maximum. The force depends on 1. magnitude of current 2. Magnetic field induction 3. Angle between the direction of current and magnetic field. Fleming's Left hand rule is used to find the direction of force acting on the rod
What determines the strength of a magnetic field?
factors on which magnetic field a bar magnet depends :- 1. pole strength of the magnet 2. medium in which the bar magnet is present(since the permittivity changes) factors on which external magnetic field(B) of a current carrying coil depends:- 1. the amount of current flowing through the conductor 2. the perpendicular distance of the point from the conductor. 3. medium in which the conductor is present(since the permittivity changes)
Why does current carrying conductor experience force when kept near a magnet?
The current carrying conductor has a magnetic field of of its own so when it comes in contact with with another magnetic field it experiences a force which is given by fleming's left hand rule.The force depends upon :direction and the strength of the magnetic fielddirection and the strenth of the current
Is CD case an conductor?
harddisks are constructed from an aluminum platter (conductor) coated with a magnetic metal oxide (insulator)floppy discs are constructed from a plastic sheet (insulator) coated with a magnetic metal oxide (insulator)however the function of computer disks in no way depends on the property of being a conductor/insulator, only on its ability to retain tiny magnetic domains while permitting them to be easily modified.
Why H2O is stationary phase in chromatography?
Water does not have to be the stationary phase. It can be the diluent. Stationary phases are a wide array of substances. The stationary phase depends on the sample being analyzed.
What changes the flow of electrons in an alternating current?
first of all the voltage doesn't change what changes is the current direction the way they do it is by using magnet . electrons tend to escape from the magnetic field . you can find on you tube how a motor works for better idea.
Is dirty water conductor or insulator?
it depends on the pollution to be a conductor
What is an earthquake's strength?
Depends on it's magnitude which can range. Seisometers are used to measure the Magnitude of an earthquake. Magnitude is it's strength.
Where does the magnitude of force depends?
it depends on:-1. no. of turns of the wire
Is a kettle handle a conductor?
it depends on what the handle is made from..if its wood or plastic then no .. but if its metal or tin then it will be a conductor.. xxx
