In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.

In this learning activity you'll build a resistor's color code based on the bands.

Learners study the fundamental operation of a triac, particularly how it is turned on and off. A brief quiz completes the activity.

Learners view the steps for testing a capacitor with an analog ohmmeter. A brief quiz completes the object.

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.
