Discharging Time Constants of an RC Circuit
By Terry Bartelt
In this animated object, learners examine how current, voltage and the discharging capacitor of a series RC changes during 5 time constants. A brief quiz completes the activity.
Interpreting Engineering Drawings: Title and Revision Blocks
By Glenn Sokolowski
Learners examine the information on a title block and answer questions about that information in an interactive quiz.
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.
In this animated activity, learners see that changing the resistance value of the load in the secondary of a transformer causes current to vary in the primary.
AC Voltage Conversion Problems
By John Rosz, Terry Bartelt
Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
The Two-Neuron Knee-Jerk Reflex Arc
By Barbara Liang
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.
The Upper and Lower Motor Neurons
In this animated object, learners examine the function and location of the motor neurons and the damage that can result when they are injured.
By Eileen Bouchard
In this animated object, learners examine how the sensory, motor, mixed, and reflex nerves work in the human body.
