In this animated learning object, users view the process of entering a formula in an Excel spreadsheet. Several different methods and associated examples are given.

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.

The learner will examine the basic characteristics of the operational amplifier integrated circuit and solve for Vout.

Learners solve for voltage, current, and power in a single source, six-resistor circuit. A help screen is provided.

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

In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.

Learners observe animations showing how data is converted between serial and parallel flow.

Learners follow a methodical approach for the dc analysis of series-parallel circuits.

In this interactive object, learners work 12 problems dealing with dc circuit analysis.

You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
