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.

Students study the concept that the voltage drop across a series circuit resistor is proportional to its resistance. They then complete a brief quiz.

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.

In this learning activity you'll explain how voltage and resistance in a series circuit affect current flow.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.
