Inductance
Inductors oppose any change in
current
What is the proper term used for the type of material placed between the plates of a capacitor?
Dielectric
These types of metallic materials are attracted to magnets
Iron, Steel, Nickel, Cobalt, and most ferromagnetic metals.
According to the Left hand Rule, when grasping a current carrying coil in such a manner that the fingers point in the same direction as the electron current in the wires, what does the thumb represent?
The thumb points towards the north pole of the coil
To produce a peak voltage by moving a conductor in a magnetic field, how must a Conductor be moved?
90 degrees through the lines of force
The opposition of an inductor to any change in current is known as
inductive reactance
Energy is stored in a capacitor by means of
its electrostatic field
The magnetic flux lines of a magnet travel in a path outside of the magnet in which direction?
From the north pole to the south pole
The self-induced voltage in a coil depends on which of the following?
The current change in the coil
When current and voltage reach their maximum instantaneous values at the same instant and in the same direction the current and voltage are considered to be
in phase
Inductive reactance is measured in
ohms
The term applies to the opposition to magnetic lines of force is?
reluctance
The left-hand generator rule states that if the thumb, index finger and middle finger are held at right angles to each other, the induced voltage will cause an electron flow
in the direction of the middle finger
Temporary magnets, which lose nearly all of their magnetism in a very short time, are described as having what?
Low retentivity
Magnetism remaining after the current flow has stopped.
Residual Magnetism
