The amount of current that flows into a transformer primary when voltage is first applied is called _____ current.
A) magnetizing
B) excitation
C) activating
D) inrush
Inrush Current
The amount of current that is drawn when an inductive device is first connected to the power line.
Magnetizing
Refers to the process of inducing magnetic properties in a material, usually by placing it within a magnetic field or by passing an electric current through it.
Excitation
The process of supplying electrical current to the field windings of a motor or generator, stimulating it to generate a magnetic field or to operate.
