Learners follow steps to trace logic signals from the inputs of several interconnecting logic gates to one output.

Learners view animations showing the operation of the internal parts of an AC generator. A short quiz completes the activity.

In this interactive object, learners review the CDR and work nine problems. Immediate feedback is given.

In this interactive object, students calculate capacitive reactance, phase angle, impedance, and power in series RC circuits.

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

Learners examine the function of the analog wattmeter to measure true power, how it is connected in a circuit, and how the internal components develop a measurement. A brief quiz completes the activity.

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.
