What is a Winding Short Circuit?
When 2 turns of an inductor or transformer short together.
What two things is the value of inductance affected by?
There are four basic factors of inductor construction determining the amount of inductance created. These factors all dictate inductance by affecting how much magnetic field flux will develop for a given amount of magnetic field force (current through the inductor's wire coil): 1. Number of turns in the coil (N) 2. Length of coil (l) 3. Cross sectional area of coil (A) 4. Material (nature, or permeability) of coil: u(Greek meu) Inductance, L=(N^2 . u.A)/l
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 formula for inductance flux leakage?
the product of number of turns and flux through the coil ........by maherbano
Why does voltage lead current in an inductor?
From what I've read, an inductor is designed to store energy in the form of a magnetic flux. A simple inductor can be thought of as a coil of wires around a medium. The current causes the flux to go through each turn of the coil. Further examination and Faraday's law leads to this model. v= N * D(magnetic flux) Because the current inside the coil is what generates the flux, the voltage will change first, before the flowing electrons will get all the way through the inductor. The inductance constant L is the Number of turns in the wire times the ratio of the current i to the magnetic flux, which is usually a constant. L = N*flux/i Which leads to this relationship between voltage and current in an inductor: v = L* D(i) The D() function being a derivative. Because the derivative of the current will change before the current actually does, voltage leads current in an inductor.
How to calculate the inductance of a home made inductor?
To calculate the inductance of a home made inductor simply take the number of turns,the magnetic flux linkage and the current and use the inductance formula.
Do the wire act as inductance?
Yes, even a straight piece of wire has inductance. One metre (or yard) of household flex has about 800nH (0.8uH) of inductance. Winding wire into coils makes them more compact, and multiplies the inductance of the assembly through coupling between turns. Using straight pieces of wire, the inductance is proportional to the length, but in a coiled inductor with 100% coupling, the inductance is proportional to the turns (length) squared! In many applications, iron or ferrite cores are used to further increase the inductance.
What is a Winding Short Circuit?
When 2 turns of an inductor or transformer short together.
The resistance that an inductor poses to the flow of ac?
An inductor has two properties. The first is resistance(measured in ohms), which is due to the length, cross-sectional area, and resistivity of the conductor from which it is wound. The second is inductance (measured in henrys), which is due to the length of the inductor, its cross-sectional area, the number of turns, and the permeability of its core.The inductor's resistance limits the value of current flowing through the inductor. The inductor's inductance opposes any change in current.
How do you double the inductance value without double the number of the turns?
In addition to the number if turns, the inductance also depends on the length and diameter of the winding, the pitch (number of turns per inch), and the material of the core if there is one. Search on line and find an empirical formula for the inductance of a finite coil, and then work to tweak the other parameters to alter the inductance as required.
Which winding has the higher resistance start or run in single phase motors?
start winding is thicker with less number of winding whereas run winding is less thicker than start winding but with more number of winding. As we know inductance depends upon numbers of turns of winding so run winding will have more inductance.

How do you construct an inductor?
any conductor wound with few turns can be considered as an inductor
What is the symbol for an inductor?
The inductor symbol resembles a coil of wire of 3 to 5 turns.
If number of turns of inductance double then its value?
"The magnetic field produced by each turn interacts with the field of other turns and multiplies the effect, causing the inductance of a coil of wire to increase by the number of turns (N) squared. Therefore, if you double the number or turns, you quadruple the inductance."
HOW Does a clamp-on ammeter measures current by capacitance?
A clamp-on ammeter does not measure current by capacitance. It forms a current transformer that operates by inductance. The clamp-on part is the magnetic core of the transformer. There is another winding inside that is coupled by the core to the line that is being measured. This second winding is shorted and the device reads the current through that winding. The current is proportional to turns ratio.
