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.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

Students read about the concept of true power and view examples of how it is dissipated as heat is provided.

This learning object will define DNA collection and methods

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.

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

This game reviews the parts of scientific method.
