Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.
The RC Time Constant
By Patrick Hoppe
Learners examine the concept of the RC time constant. The instantaneous voltage across the capacitor is calculated.
Electric Pencil Sharpener: Process Planning
By Amy Gau
Students view photos of an electric pencil sharpener as it is disassembled. The learning object is intended to prepare students to be able to identify the components and create an assembly process in a future activity.
Continuous-Cycle Reciprocation Circuit
By Terry Bartelt
This animated lesson shows how a ladder circuit causes the cylinder of a hydraulic circuit to continuously extend and retract after a Start button has been pressed.
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.
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.
AC Voltage Conversion Problems
By John Rosz, Terry Bartelt
Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
AC Voltage Conversions
In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.
