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

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

In this learning activity you'll review the process of solving for the total resistance in a series DC circuit.

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

Students work nine practice problems to determine total series inductance. Immediate feedback is given.

The learner will calculate basic circuit resistance.

Learners examine the concept of propagation delay within a TTL logic gate. The concept is explained with the use of timing diagrams and sample calculations.

Learners read how the NOR gate can be configured to obtain the other common logic gates. Schematics and Boolean expressions demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NOR gates

Learners read how to calculate the MOD number and how it is used.

Learners test their knowledge of the variations of Watt's Law and Ohm's Law with this quiz.

In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.

Students look at the power dissipated by a single gate and by an IC. The concept of average current draw is introduced and examples are provided.

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

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

Learners follow the steps for reducing all of the elements of a complex circuit to a single current source and a single source resistance to create a simple circuit. Several examples are given for dc circuits. The conversion between Thevenin and Norton is also presented.

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

Students view schematics and truth tables that demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NAND gates.

Learners work practice problems to calculate the total resistance of a circuit. Feedback is provided.

Learners read a description of inductors and view examples of inductors in series and in parallel.

In this animated object, learners examine the basics of capacitance and capacitors.
