In this animated activity, learners examine the operation of a pneumatic cylinder that continuously cycles by extending and retracting.

Learners examine a general approach to solving for the current through, the voltage across, and the power dissipated by each resistor in a series DC circuit. A three-resistor series circuit is used as an example.

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

The learner will understand the operation of motor control circuits used to start and stop three-phase motors.

In this learning activity you'll apply the Pythagorean Theorem to isosceles and equilateral triangles.

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

In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.

Students read an explanation of "superposition" as a technique for ac circuit analysis. Complex numbers are used.

Students read how to determine the total impedance of a parallel circuit using complex numbers. The "J" term is used in the calculations.
