This learning activity describes the abilities of an inductor coil to oppose alternating current and to pass direct current.
Students read about the process of hair growth beginning with the joining together of amino acids.
Students view the parts and movements of a combustion engine in this animated activity. Each part is described.
This learning activity describes the physical properties that affect the inductance, in henries, of an inductor.
In this animated lesson, learners examine the rectifier circuitry in a DC variable speed drive that supplies the voltages to the field coil and armature.
In this animated object, learners examine how a coil of wire provides more resistance to AC current flow than an uncoiled wire. This learning object contains audio.
Learners examine how an electromagnet is formed. Animated illustrations show current running through a coil wrapped around an iron core.
In this animated object, learners observe the changes inside the DC shunt motor that could cause the motor to break apart when its field coil opens. A short quiz completes the activity.
Learners study the operation of a ladder circuit in which coils on one rung control contacts in other rungs.
Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.
Learners view animations showing how electrical signals are applied to the coils of a stepper motor to perform microstepping. A short quiz completes the activity.
In this 3D animated object, learners examine the way in which a three-phase generator produces three sine waves with three armature coils. A quiz completes the activity.
