Students view drawings of the emitter resistor bypass capacitor.
Oscilloscope Phase Shift Measurements
By Terry Bartelt
In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.
Logic Probe Troubleshooting
In this animated object, learners follow a process for troubleshooting digital integrated circuits on a printed circuit board using a logic probe.
PID Control (Screencast)
Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.
Series-Parallel Circuit Analysis Practice Problems: Circuit #5
By Patrick Hoppe
Learners examine a series-parallel circuit and solve 14 problems related to voltage, current, and power. A help screen is provided.
Parallel RC Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
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.
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.
