Students view the steps for determining the total capacitance for a series circuit. They then work practice problems.

The learner solves for Zin(base), Zin(stage), Zout, and Av. A "help" screen is available.

Students view a video that shows the correct methods for starting a GTAW weld pool and adding filler. It focuses on the two problems that many students have – adding filler too soon and angling the torch so that the filler melts prematurely on the filler rod. Note: This activity is 3.6 mb.

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.

In this learning activity you'll practice converting between hexadecimal and decimal and between hexadecimal and binary numbers.

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

Students answer 10 questions in a sample exam. This exercise covers number systems, number conversion, logic gates, and combinational design. Feedback is provided.

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.

This game will quiz you on your knowledge of digital citizenship!!
