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 interactive object, learners calculate a centroid of a composite area by first creating a chart. A short quiz completes the activity.

Learners examine three formulas than can be used to find dc power. Examples are given.

In this animated and interactive object, learners examine the basic parts and the linear movement of a hydraulic cylinder. A brief quiz completes the activity.

In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.

In this animated object, students view an explanation of how current, voltage, and the charge on a capacitor of a series RC circuit change during five time constants. A short quiz completes the activity.

In this animated object, learners examine how current, voltage and the discharging capacitor of a series RC changes during 5 time constants. A brief quiz completes the activity.

In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.

In this animated object, learners view the keystrokes on a TI-30XIIS calculator that are required to solve for the instantaneous voltage of a discharging RC circuit.
