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.
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.
What is dynamic impedance?
The impedance of a circuit having an inductance and a capacitance in parallel at the frequency at which this impedance has a maximum value. Also known as rejector impedance.
What are advantages of ac bridges?
ac bridges give the value of impedances like inductance, capacitance with high accuracy. it also tells us about the quality factor .
In C plus plus all false relational expressions have a mathematical value of?
In C++ all false relational expressions have a mathematical value of 0.
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)
Raising a fraction to higher terms does change the value of the fraction. True or false?
False.
What is the unit of measurement of inductance?
Inductance is measured in Henrys
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.
True or False The assessed value of a home is always higher than its market value True or False The seller must fix all needed repairs discovered during the home inspection?
Both are false.
How does a Maxwell bridge operate?
it is used to measure the unknown value of inductance
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.
What is an inductor and its current rating?

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
Is this statement true or false the absolute value of a number is less than the original number?
It is false because if it is the absolute value of a negative number, the answer would be higher than the original number. |-9|=9
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.
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."
