Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
Excel: Entering a Formula
By Patrick Hoppe
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.
Voltage Waveforms in an Edison Three-Wire System
By Terry Bartelt
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.
Op Amps 1: The Operational Amplifier
By Todd Van De Hey
The learner will examine the basic characteristics of the operational amplifier integrated circuit and solve for Vout.
Series-Parallel Circuit Analysis Practice Problems: Circuit 6
Learners solve for voltage, current, and power in a single source, six-resistor circuit. A help screen is provided.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
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.
Series-Parallel DC Circuits Analysis
Learners follow a methodical approach for the dc analysis of series-parallel circuits.
