Inductors
True or False

Mark each of the statements below True or False.

1 .       The term choke is more commonly used in connection with an inductor used to block off high frequencies. [Hint]

 
 


2 .       All coil cores are made of iron. [Hint]

 
 


3 .       An induced voltage is produced as a result of a dc voltage. [Hint]

 
 


4 .       Inductance is the property of an inductor that produces an opposition to any change in current. [Hint]

 
 


5 .       Faraday's law states that relative motion between a magnetic field and a coil induces a voltage across the coil. [Hint]

 
 


6 .       Energy is stored by an inductor in an electrostatic field. [Hint]

 
 


7 .       Inductance is indirectly proportional to the square of the number of turns, the permeability, and the cross-sectional area of the core. [Hint]

 
 


8 .       The permeability of a core material is an indication of the ability of the material to establish a magnetic field. [Hint]

 
 


9 .       Inductors add in parallel. [Hint]

 
 


10 .       XL is directly proportional to frequency and inductance. [Hint]
