In this interactive object, learners answer 25 questions regarding part or assembly drawings. The basic areas of blueprint reading are covered.

Learners answer questions about nonferrous metals and alloys using a game show format. Immediate feedback is provided.

In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Learners study how a circuit converts the AC output of a linear voltage differential transformer (LVDT) into variable DC voltage. It is recommended that learners view the learning object IAU7807, “The LVDT: A Linear Voltage Differential Transformer in Action” before going through this object.

In this interactive and animated object, learners practice testing a diode. They determine if a diode is good, open, or shorted.

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

This learning object introduces the three approximations of a diode.

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

This primer introduces the student to the half-wave rectifier. Both the 1st and 2nd approximations are examined.
