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.

Can capacitance be negative?
no, if it was it would act like inductance.
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.
Does frequency effect total inductance?
Inductance is inductance, and is not a function of frequency. Frequency affects reactance, and ultimately impedance, not inductance.
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 factors increase the inductance of a coil?
what factors on inductance drepends
Can capacitance be negative?
no, if it was it would act like inductance.
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
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.

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
What does the dot on a current transformer mean?
There is a method called dot convention which is used in transformers. the dot shows the direction of current flowing through the coil and whether the value of mutual inductance thus produced will be positive or negative.
When the frequency in Hertz and the reactance positive or negative in Ohms are known can you determine component values such as inductance or capacitance?
Positive
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."
