Learners read about the vector diagram for a parallel RC circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.

In this interactive object, learners solve additional problems involving total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

Learners study animations showing the integral function of a closed-loop control system and the difference between the two types of integral controller settings, reset rate and reset time. A short quiz completes the activity.

Learners read how to convert complex numbers to their polar equivalent in Excel.

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.
