In this animated and interactive object, learners examine the inverse proportionality of wavelength and frequency and their relationship to the speed of light.
Learners study animated rheostat settings that show how current flow is inversely proportional to resistance. Ten review questions complete the learning object.
In this animated object, learners view a race of two boats as an example of how the derivative function of a PID controller shortens the time duration of an operation.
Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.
Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.
