An ohmmeter is connected across an inductor and the pointer indicates zero ohms. The inductor is
Faraday's law states that relative motion between a magnetic field and a coil induces a voltage across the coil.
An induced voltage is produced as a result of a dc voltage.
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.
