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.
Parts of Speech in Sentences: The Order of Operations
Learners identify the parts of speech by following a certain order until each word in a sentence is labeled. In a variety of exercises, learners practice finding verbs, prepositional phrases, subjects, nouns, pronouns, adjectives, adverbs, and conjunctions.
In this learning activity you'll identify the various parts of a bar graph, read and interpret its data, and calculate the data to solve various application problems.
Bloom's Taxonomy For Cognitive Learning and Teaching (Screencast)
The users of this learning object read a brief introduction to the six levels of Bloom's Cognitive Taxonomy and quiz themselves on a basic understanding of the levels.
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 learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.
In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.
In this interactive object, learners read a brief summary of the principles of cash basis accounting and then check their knowledge of transactions in a drag-and-drop exercise.
Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.
Learners study animated rheostat settings that show how current flow is inversely proportional to resistance. Ten review questions complete the learning object.
