Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
By Terry Bartelt
In this animated and interactive object, learners examine the interaction between a conductor that represents a motor armature and a magnetic field that represents a motor’s main field. This interaction causes the shaft to turn.
The Differentiator Op Amp
In this animated object, learners examine the circuit configuration and operation of a differentiator operational amplifier. A brief quiz completes the activity.
Motor Speed Control
Learners examine the speed control circuits in a DC variable speed drive that cause the RPM of a motor to vary. This activity has audio content.
The Planets: Mars
Mars is the fourth planet from the Sun. Presently, information is being relayed from nine active probes on or in-orbit around Mars, including six orbiters and two rovers. Recently, Europe's ExoMars mission landed on Mars on October 19th 2016.
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
By Patrick Hoppe
Learners follow a methodical approach for the dc analysis of series-parallel circuits.
Series-Parallel Practice Problems Circuit 4
In this interactive object, learners work 12 problems dealing with dc circuit analysis.
The Op Amp Non-Inverting Amplifier Configuration
You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
This is a great tool!
