In this animated learning object, students read about the operation of a half-wave rectifier.

Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.

Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units.

In this interactive object, learners solve additional problems involving total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

In this animated object, learners examine the operation of a zener diode in the forward and reverse bias conditions. A quiz completes the activity.

Learners view the operation of a full-wave rectifier which has two diodes.

Learners see how a bridge rectifier converts an AC voltage into a pulsating DC voltage. A brief quiz completes the activity.

In this animated learning object, students read about the operation 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.
