Causes and Risk Factors of Cerebral Vascular Accidents
In this interactive object, the learner examines the causes, symptoms, and risk factors associated with a stroke. The terms "thrombus," "emboli," and "hemorrhage" are defined. A self-assessment of risk factors completes the activity.
Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.
Op Amp Fundamentals: The Transconductance Amplifier
Students read an introduction to the transconductance amplifier. They also view formulas for voltage-to-current conversion, closed-loop input, and output impedance. An example of how R1 controls the conversion factor is given.
In this animated object, learners examine the factors that determine how well a capacitive proximity sensor can detect an object. Those factors include size, position, and the materials from which the target is made. A brief quiz completes the activity.
Learners consider the factors that determine how well an inductive proximity sensor can detect an object. Those factors are size, position, and the material from which the target is made. A brief quiz completes the activity.
In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.
Identify your self-awareness score. In this learning activity, you'll answer 24 questions that attempt to measure three factors relating to self-awareness: introspection, public self-consciousness, and social anxiety.
