Students read about the six common terms used to represent the powers of ten in the field of electronics and complete two matching exercises.

This animated object allows students to examine the four steps used to reduce a complex circuit to a simple series circuit.

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

In this interactive object, students complete progressively more difficult exercises as a way to improve their ability to recognize resistor color code values.

In this learning activity you'll practice calculating the between the binary number system and the decimal number system.

Students read an explanation of power factor correction. Examples of both inductive and capacitive loads are given.

Learners examine first and second approximations and view examples of a "stiff" current source.

In this learning activity you'll review the operation of an Exclusive-NOR gate by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

In this interactive object, students calculate inductive reactance, impedance, current, and power in parallel RL circuits.

Learners read an explanation of the RL time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero. Note* In the formulas in this module, the Greek letter epsilon should be the mathematical constant 'e'.
