Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.

In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.

Learners examine the operation of a DC Shunt motor and its characteristics. A quiz completes the activity.

The learner will understand how to correctly wire a three-wire sinking and sourcing sensor.

Learners review the process for calculating board feet and use virtual samples to practice the process.

Learners read how to use a lumber rule to quickly and accurately estimate board feet. They then use virtual samples to practice the process.

In this learning activity you'll be introduced to the layout and operation of the solderless breadboard.

Learners review the process for calculating board feet and use virtual samples to practice the process.
