In this animated activity, learners examine the conversion of electrical energy into an electrostatic charge within the dielectric material of a capacitor.

In this learning activity you'll review the process of solving for the total resistance in a series DC circuit.

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.

Learners study the process of mathematically converting temperatures between the Fahrenheit and Celsius scales. A short quiz completes the learning object.

Learners examine the speed control circuits in a DC variable speed drive that cause the RPM of a motor to vary. This activity has audio content.

In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.

Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.
