True or False
Mark each of the statements below True or False.
1 .

choke
is more commonly used in connection with an inductor used to block off high frequencies.
[
Hint
]
True
False
2 .
All coil cores are made of iron.
[
Hint

True
False
3 .
An induced voltage is produced as a result of a dc voltage.
[
Hint
]
True
False
4 .
Inductance is the property of an inductor that produces an opposition to any change in current.
[
Hint
]
True
False
5 .
Faraday's law states that relative motion between a magnetic field and a coil induces a voltage across the coil.
[
Hint
]
True

6 .
Energy is stored by an inductor in an electrostatic field.
[
Hint
]
True
False
7 .
Inductance is indirectly proportional to the square of the number of turns, the permeability, and the cross-sectional area of the core.
[
Hint
]
True
