Learners examine the operation of the on-off control mode using a home heating example. A short quiz completes the activity.

Learners read an explanation of the RL time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero. Note* In the formulas in this module, the Greek letter epsilon should be the mathematical constant 'e'.

In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.

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

Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.

Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.

In this interactive object, students view an animated depiction of Class 1 levers. A matching quiz completes the activity.

In this interactive object, students view an animated depiction of Class 3 levers. A matching quiz completes the activity.

Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.
