In this animated object, learners study how displacement level sensors are used to measure the level of liquid in a tank.

In this animated object, students view diagrams of the UJT as it is used in the relaxation oscillator circuit. Waveforms illustrate how the circuit operates through several time periods.

Students work practice problems in which the total resistance of the circuit is calculated. Feedback is provided.

Learners view an animated explanation of why an adjustment of the output voltage by an AC drive is required to maintain a constant torque as the frequency is varied.

In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.

In this interactive object, learners calculate a centroid of a composite area by first creating a chart. A short quiz completes the activity.

In this animated and interactive object, learners calculate the area and centroid of a rectangle.

In this animated and interactive object, learners calculate the area and centroid of a triangle.
