What else can I help you with?
Contains both resistance and inductance?
Wire. conductors. Wire made into a coil, an inductor.
What will increase inductance?
in many ways..by adding coil,increasing frequency ,made coil smaller,inserting rods inside the coil,physical position adjustings..and so on.the fact is many factors are involving in inductions.
Why is it that if you take a piece of Copper wire and plug it into a power supply it creates a short circuit but if the same wire is coiled then it acts as an inductor and doesnt make a short circuit?
=== === This answer assumes the wire is properly insulated along its length so that it does not have any shorted turns if it is wrapped around a core made of a good insulator such as wood or plastic. Whether or not it is wound into a coil the resistance of a piece of copper wire depends on how long and thin it is. The thinner and longer the wire, the higher the resistance it will have and the less current it will draw from the power source.A very short piece of thick wire will have such a low resistance it will take so much current that it will behave just like a short circuit. (Whether it is insulated or coiled even a little bit will make no difference.)If a sufficiently long length of insulated wire is made into a coil it will act as an inductor. If it is wound around a cardboard or wooden core containing a piece of iron, the iron would make the coil have a much higher inductance than for just air.
Why the inductor heat up?
Temperature affects the resistivity of materials which, in turn, affects their resistance. For pure metal conductors, their resistance increases with temperature. As an inductor is often made from a coil of copper wire, its resistance will increase whenever its temperature increases. If it is important for the resistance to remain constant over a wide variation of temperature, then alloys, such as constantin, are used instead of copper. These alloys maintain an approximately-constant resistance over a wide range of temperatures.
Definition of a resistance-start induction run motor?
Resistance start-induction run motors are commonly known as split phase. They are only single phase motors. They have 2 sets of windings, the Start winding which is high resistance and low inductance made for thin wire, and the Run winding which is low resistance and high inductance made for thick wire. The 2 windings are set skewed about 30 degrees on a twist. This is to create the angular rotary motion, which is what a motor is all about. On start up both start and run windings are energised. Some form of switch disconnects the start winding when the motor is about 75% up to speed, and only the run winding remains in the circuit. There you have it.....

Why in coil power factor is low?
A coil of wire acts as an inductor; it will have a very small resistance, and a relatively large inductance. Power factor is effectively the resistance divided by the impedance (made up of resistance and inductance), so the larger the inductance relative to the resistance, the lower the power factor will be.
Why doesnt a field coil in a DC shunt motor lead to short ciruit when it is a fact that an INDUCTOR is a short circuit to DC?
Yes, an inductor is a short circuit to dc...that's true....IF the inductor is an ideal one, that is, the inductor has no resistance but has inductance only. Anything in real world, as you know, is not ideal. An inductor is usually made of a copper wire. A copper wire has its own resistance. If an inductor coil is thin and long (i.e. many turns), it will provide an appreciable resistance to DC, and will no longer be a short circuit.
What is the relationship between the length, material, and inductance of a wire?
The relationship between the length, material, and inductance of a wire is that the inductance of a wire increases with its length and the type of material it is made of. A longer wire and a wire made of a material with higher conductivity will have higher inductance.
Inductor and capacitor?
An inductor is a magnetic device that resists a change in current. It is constructed with windings that can be backed by ferro-magnetic cores. The equation of an inductor is ... di/dt = V/L ... meaning that the rate of change of current per time is proportional to voltage and inversely proportional to inductance. Inductors, since they work on magnetic fields, can be coupled, as transformers, motors, and generators. A capacitor is a charge device that resists a change in voltage. It is constructed with parallel plates. The equation of a capacitor is ... dv/dt = I/C ... meaning that the rate of change of voltage per time is proportional to current and inversely proportional to capacitance. Inductors and capacitors, since they work in opposite phasor angles, can be coupled to make resonant filters, giving bandpass or bandcut to particular frequencies.
Are inductors measured in ohm's Henry's or reactance?
Inductors can be measured in all three of the above:When an the value of an inductor is given in henrys you are being given its "capacity" to store energy in a magnetic field.Because the inductor is not made of a perfect conductor (one without resistance) it will inevitably has some associated resistance. This is the value that is being referred to if the value of ohms is given.If an inductor is part of an AC (alternating current) circuit it will have a changing "resistance" (resistance as seen by the source) that is directly related to the frequency of the circuit. This is where the reactance value would be given. It equation is given as: 2*pi*f*L. Where f is frequency in hertz and L is the inductance given in henrys..
What is the relationship between the inductance of a straight wire and its physical properties?
The inductance of a straight wire is directly related to its physical properties such as length, cross-sectional area, and material composition. A longer wire with a smaller cross-sectional area and made of a material with higher conductivity will have higher inductance.
What is the inductance of a straight wire?
The inductance of a straight wire is a measure of its ability to store energy in the form of a magnetic field when an electric current flows through it. It depends on the length and diameter of the wire, as well as the material it is made of.
Is a circuit a path made for magnetic field?
A circuit is a path for charge particles -- it conducts current. An inductor, a circuit component, generates a magnetic field, when an AC is on. ======================
What is centre tap transformer?

How do you make a TI83 calculate wrong?
You cannot. A calculator is programmed. It is made to calculate correctly.
What is You Tube in Engineering Terms?
During the Old Days As Electricity evolved trough the world, Electronics came up. (You) Tube or Conduit is what they called to this electronics parts they place in Television or Radio. This are Capacitor, Inductor, Resistance, etc made in a big material made of Glass Tube or Glass Conduit they called. This Capacitor. Inductance, Resistance are now made Digital Electronics which place inside our Flat Television, Small Radio, Modern Camera, Computer (Desktop or Laptop), etc. Now i will name some of few how they call this now. X gate. Y gate, Or gate, Nor gate, Grid place in a small digital elctronic which we used today.
