In this animated lesson, students view how an oscilloscope and a DC voltmeter measure the voltage of a half-wave rectifier.
In this learning activity you'll explore the operation of a full-wave bridge rectifier circuit.
In this animated object, students observe how the pulsating DC output voltage of a full-wave rectifier is filtered by a capacitor.
In this animated learning object, students read about the operation of a half-wave rectifier.
This primer introduces the student to the half-wave rectifier. Both the 1st and 2nd approximations are examined.
Learners see how a bridge rectifier converts an AC voltage into a pulsating DC voltage. A brief quiz completes the activity.
Learners view the operation of a full-wave rectifier which has two diodes.
Students examine the full-wave rectifier. They review appropriate formulas and examples of actual circuits.
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.
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.
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.
