In this animated lesson, students view how an oscilloscope and a DC voltmeter measure the voltage of a half-wave rectifier.
In this animated object, students observe how the pulsating DC output voltage of a full-wave rectifier is filtered by a capacitor.
Learners view the operation of a full-wave rectifier which has two diodes.
In this learning activity you'll explore the operation of a full-wave bridge rectifier circuit.
This primer introduces the student to the half-wave rectifier. Both the 1st and 2nd approximations are examined.
Students examine the full-wave rectifier. They review appropriate formulas and examples of actual circuits.
In this animated learning object, students read about the operation of a half-wave rectifier.
Learners see how a bridge rectifier converts an AC voltage into a pulsating DC voltage. A brief quiz completes the activity.
In this animated activity, learners examine the operation of the SCR, including how it is biased and how it is turned off. A brief quiz completes the object.
Learners view waveforms at various locations of an SCR circuit controlling the intensity a light bulb. The waveforms are shown when the light is dim, at medium brightness, and at full brightness. A brief quiz completes the activity.
In this learning activity, learners will learn to calculate the average voltage produced by half-wave and full-wave rectifiers.
Learners examine the circuitry in a DC variable speed drive that protects the rectifier diodes and motor windings from being damaged due to excessive current.
In this animated lesson, learners examine the rectifier circuitry in a DC variable speed drive that supplies the voltages to the field coil and armature.
