Learners examine the connections of a DC motor and how the terminals are labeled. A matching exercise completes the learning object.

Learners examine the ways in which a motor starter circuit is protected by a main circuit breaker and overload heaters when there is excessive current.

The learner solves for Zin(base), Zin(stage), Zout, and Av. A "help" screen is available.

Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.

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

Students view a sample of the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous current of a de-energizing circuit.

Students view a sample of the keystrokes used on a TI-36X calculator to solve for the instantaneous current of a de-energizing circuit.

Learners view a sample of the keystrokes on a TI-36X calculator that are required to solve for the instantaneous current of an energizing RL circuit.
