Inductors are also known by any of these three other descriptive names.
What is a coil, a choke, or a reactor?
100
The opposition to alternating current that is provided by inductance is known as this.
What is inductive reactance?
100
The CEMF or BEMF produced when an inductive circuit is opened is known by this physical name.
What is inductive kick?
100
Inductance in series does this.
What is adds?
100
This is a device that opposes a change in current.
What is an inductor?
200
These inductors have a doughnut shaped core.
What is toroid?
200
Inductive reactance is said to be directly proportional to the inductance of the coil and to this other factor. It happens all the time...
What is frequency?
200
Inductors in an AC circuit return their energy to the source this many times during each cycle of the signal.
What is twice?
200
Inductive reactance in series does this.
What is adds?
200
Hey Joe! This is the base unit of inductance.
What is the Henry?
300
This inductor chokes off frequencies used in broadcasting.
What is an RF inductor?
300
Inserting a ferrite core into the center of an air core inductor will have this affect on the inductor's reactance.
What is increase it?
300
The shield of an inductor should be connected to this to limit electromagnetic interference.
What is ground?
300
A 10 mH inductor is in parallel with a 20 mH inductor which produces this inductance total.
What is 6.667 mH?
300

In a perfect world this type of inductor converts no electrical energy into heat energy.

What is an ideal inductor?

400
This type of inductor has many thin layers of metal sandwiched together to make up its core.
What is a laminated iron core?
400
Don't hold back... The quality or Q of an inductor is a ratio of inductive reactance and this other quantity.
What is resistance? (Q = XL / R)
400
Don't be a square! The current lags the voltage in an inductive circuit by this number of degrees.
What is 90?
400
Three inductors are in series with each other and they are each .5 H creating this amount of total inductance.
What is 1.5 H?
400

Two electrically isolated inductors can be magnetically coupled together by this phenomenon.

What is mutual inductance?

500
The moveable core inside an adjustable inductor is known by this name.
What is a slug?
500
Two 20 mH inductors are in series with a 5 kHz source which results in this much inductive reactance.
What is 1,256 ohms?
500
The smallest inductor always carries the most current when the inductors are placed in this electrical configuration.
What is parallel?
500
This is the Quality of a 30 mH inductor that has a whopping 40 ohms of resistance and is connected to a 5 volt, 20 kHz source.
What is 94.2?
500

Call my dermatologist!  The "skin effect" can be reduced by using this specialized multistrand wire.

What is Litz wire?
