Impedance

Whenever inductive and capacitive components are used in an AC circuit, the calculation of their effects on the flow of

Capacitors The variation of an alternating voltage applied to a capacitor, the charge on the capacitor, and the current flowing

As previously stated, any change in current in a coil (either a rise or a fall) causes a corresponding change

Inductance Any device relying on magnetism or magnetic fields to operate is a form of inductor. Motors, generators, transformers, and

Analysis of the AC power generation process and of the alternating current we use in almost every aspect of our

An understanding of how an AC generator develops an AC output will help the student analyze the AC power generation

At the moment a DC motor is started the armature is stationary and there is no counter EMF being generated.

Since the armature and field in a series-wound motor are connected in series, the armature and field currents become identical,

The speed-torque relationship for a typical shunt-wound motor is shown in Figure 8. A shunt-wound DC motor has a decreasing

There are various types of DC motors found in industry today. Each type contains various characteristics that makes it desirable
