Students read an explanation of reactive power in a power distribution system involving motors, generators and transformers. A brief quiz completes the activity.
In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.
Learners read an explanation of the concept of apparent power in a power distribution system involving motors, generators, and transformers. A quiz completes this interactive lesson.
Learners examine the circuitry in a DC variable speed drive that protects the rectifier diodes and motor windings from being damaged due to excessive current.
In this animated activity, learners examine the circuitry in a DC variable speed drive that causes the motor to accelerate or decelerate at slow rates. This learning object has audio content.
In this animated activity, learners examine the circuitry in a DC variable speed drive that keeps the motor running at a constant speed as the load varies.
In this animated activity, learners examine how the speed of a motor may change if the voltage from the power source fluctuates due to power line irregularities. This lesson has audio content.
This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.
In this interactive and animated object, learners read a description of the number, name, and function of the cranial nerves. A matching quiz completes the activity.
In this interactive object, learners examine the neuron pathway into and out of the spinal cord. They complete the activity by testing their knowledge of vocabulary and the location of spinal cord structures.
