This learning activity uses a water pressure analogy to present the concept that voltage pressure is required to cause current flow.

The learner will describe the non-inverting op-amp configuration and calculate the circuit gain.

In this animated object, learners examine the operation and programming requirements of a PLC Examine-Off instruction. A brief quiz completes the activity.

Learners examine the fundamental concepts of sequencer output instruction. A simulated example shows a sequencer in operation.

Learners follow the steps required to perform the Ziegler-Nichols reaction curve process identification procedure.

Learners study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.

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 view a horizontal curve and mouse over the diagram to read descriptions of its components and related equations.

The learner calculates the resultant of multiple forces acting in a concurrent, coplanar load condition.
