Learners view a demonstration of Kirchhoff's Voltage Law using complex numbers for an ac circuit.

Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity.

In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.

Learners follow a methodical approach for the dc analysis of series-parallel circuits.

Learners read about the purposes of balance sheets and income statements and then place accounts into these two financial statement categories in a drag-and-drop exercise.

Learners listen to an explanation of balance sheet basics for farm operations. They then determine how purchases should be listed in a farm record book and complete sample income and expense sheets.

In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.

In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.

In this animated and interactive object, learners view American National Standard and International Standard sheet sizes. A quiz completes the activity.
