Students read an explanation of power factor in a power distribution and how it can be improved by using a power factor correction capacitor bank. A brief quiz completes the activity.

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

Students read an introduction to the transconductance amplifier. They also view formulas for voltage-to-current conversion, closed-loop input, and output impedance. An example of how R1 controls the conversion factor is given.

Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.

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.

This primer introduces the student to the proper method of complex number conversion on a TI-86 calculator.

In this learning activity you'll factor an algebraic expression of the form AX(Squared) + BX + C using the FOIL technique.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

In this animated and interactive object, learners follow two rules to write unit conversion fractions.

Learners quiz themselves on the conversion factors within and between the metric, apothecary, and household systems.

The conversion from rectangular to polar mode phase angle in radians is demonstrated in Excel.

Learners view the conversion factors within and between the metric, apothecary, and household systems. A quiz completes the activity.

Learners observe animations showing how data is converted between serial and parallel flow.

In this interactive object, the learner examines the causes, symptoms, and risk factors associated with a stroke. The terms "thrombus," "emboli," and "hemorrhage" are defined. A self-assessment of risk factors completes the activity.

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

Learners study how a circuit converts the AC output of a linear voltage differential transformer (LVDT) into variable DC voltage. It is recommended that learners view the learning object IAU7807, “The LVDT: A Linear Voltage Differential Transformer in Action” before going through this object.

Learners examine how to convert numbers from rectangular to polar form and from polar to rectangular form using a TI-83 Plus calculator.

In this learning activity you'll factor problems using the difference of two perfect squares.

Students view the formulas to be used to convert a series impedance to a parallel impedance.
