Learners follow step-by-step instructions for using an oscilloscope to measure DC voltages.

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.

This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.

This primer introduces the student to the correct method of using the internal memory of a TI-86 calculator.

Students solve problems on the determination of total inductive reactance of series-parallel inductors.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

This learning activity presents information on how the type of material used for the core material of an inductor affects the inductors value in henries.

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.
