An induced voltage is produced as a result of a dc voltage.

More Questions from Inductors

• Inductance is the property of an inductor that produces an opposition to any change in current.
• XL is directly proportional to frequency and inductance.
• Inductance is indirectly proportional to the square of the number of turns, the permeability, and the cross-sectional area of the core.
• The permeability of a core material is an indication of the ability of the material to establish a magnetic field.
• Inductors add in parallel.
• Energy is stored by an inductor in an electrostatic field.
• The term choke is more commonly used in connection with an inductor used to block off high frequencies.
• All coil cores are made of iron.
