This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.

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.

In this animated object, students view an explanation of how current, voltage, and the magnetic field strength of a series RL circuit change during five time constants. A brief quiz completes the activity.

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.

Describe the inverting op-amp configuration and calculate the circuit gain.

Understand the op-amp buffer configuration and calculate basic circuit impedance.

The learner will calculate basic circuit resistance.

In this animated object, learners see how a time proportioning operational amplifier varies an average DC voltage. A brief quiz completes the activity.

Students read an explanation of the operation of an operational amplifier that functions as a comparator.
