"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."

What is the magnetic quantum number value for an element with n 1?
The magnetic quantum number value for an element with n=1 is the K shell.
What best descibes induction?
Inductance is the property of a passive circuit to produce a voltage that is proportional to the rate of change of the current through it. Inductance is defined by the formula: V = L di/dt So an inductor of 1 Henry develops a voltage of 1 v across it when the current through it is changing at 1 amp per second. This is why a DC circuit with inductance is difficult to switch off, because the inductance produces a high voltage when the switch is tripped (because the current is changing very quickly). In an AC circuit the alternative formula is: V = jwL. In this case w is 2pi times the frequency in Hz and the 'j' indicates a 90-degree phase advance in the voltage relative to the current (in the formula 'w' is normally written as a small Greek letter omega but we don't have a Greek font on here).
What is the value of a Belknap Bluegrass double bit axe?
i would probably say 40 - 60 dollars depending on the shape of axe.
Which atomic number is the threshold value below which fusion may occur?
66
What is the first quantum number of a 1s2 electron in phosphorus?
The first quantum number (n) represents the energy level (shell), so for a 1s2 electron, it would have a value of 1.
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.
What will be the voltage in an inductance reactance circuit?
The voltage across the inductance alone will be(value of the inductance) times (the rate at which the current through it changes)
What is the unit of measurement of inductance?
Inductance is measured in Henrys
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 inductance value is negative?
Inductance is not negative. It is measured in henrys, and that is a positive value. Inductive reactance, however, is measured in ohms, and is commonly shown as negative to indicate that the current lags the voltage.
How does a Maxwell bridge operate?
it is used to measure the unknown value of inductance
What does it mean when your value in a chart in excel turns red or has brackets around them?
The value is a negative number.
What is the time constant of a 50mH inductor in series with a 200 ohm resistor?
You need to convert the inductance value to henry. Then, simply divide the inductance by the resistance.
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.
What is an inductor and its current rating?
An inductor is an electrical component, usually a coil, designed to offer a specific value of inductance (measured in henrys). As the operating current of an inductor affects its inductance its inductance value (inductors are not linear devices, due to their hysteresis characteristics) is normally expressed for a specific range of operating currents.
Why rotor slots is more than stator slots in induction motor?
rotor slot more. it is to get a large rotor inductance value of inductance the stator windings
When is a value called absolute?
In mathematics, the absolute value of a given number is the positive form of the number, for example, if the answer to a problem turns out to be plus or minus 3, then the absolute value is 3.
