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

In this animated and interactive object, learners examine how changes in applied voltage affect the current and voltages in a zener diode voltage regulation circuit. A short assessment completes the activity.

In this video, we’ll identify the parts that make up the Bridgeport and learn how it works.

Students complete a sample exam for DC/AC I. It provides an overview of the material presented in the course.

Students read a step-by-step approach on how to connect a voltmeter to a circuit when making a measurement.

Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. A brief quiz completes the activity.

In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.

Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.

In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.

You'll be introduced to switching within text files and using regular expressions.

You'll practice defining terms related to spheres and identifing parts of spheres.

You'll find the standard-position angle for a given reference angle.
