Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.

In this animated object, learners examine the fundamental operation of a noninverting operational amplifier. A brief quiz completes the activity.

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.

Students read about the ENTRY, INS, and DEL keys and view a demonstration of how to edit and insert characters and recall previous entries.

Learners follow the steps for adding and subtracting signed numbers and complete practice exercises.

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

In this interactive object, learners examine the physical facets that determine the value of a capacitor. A brief quiz completes the activity.

This learning activity presents information on how the type of material used for the dielectric of a capacitor affects the capacitor's value in farads.

Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
