Formulas and Functions in Microsoft Excel

A learning object to illustrate the right way to enter formulas and functions in Excel.

In this learning activity you'll create strategies for sending and receiving complaints and requests.

Use Ohm's law, Watt's law, and the power equation to derive formulas for the DC power wheel.

In this interactive object, learners complete dental formulas for various species of animals.

Students read an explanation of chemical formulas in this animated activity. A quiz completes the object.

In this module we will explore some commonly used formulas for area and volume.

Learners follow a four-step process to determine the empirical formula of a compound from the masses of its constituent elements. The molecular formula is determined in a fifth step using the molecular weight of the compound.

In this learning activity you'll identify abbreviations that represent quantities associated with electrical circuits.

Students use algebra to rearrange formulas and solve for the missing volume, density, or mass quantity.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

Students read an explanation of the summing amplifier and the formulas for closed-loop gain. An example is given.

The inverting amplifier configuration is presented. The closed loop voltage gain and the closed loop bandwidth formulas are explained, along with the concept of negative feedback.

The current-to-voltage conversion of the transresistance amplifier is examined. The formulas for output voltage and impedance are defined and an example ties the concepts together.

In this interactive object, learners examine the operation of an inverting operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.

Students examine the drain curves for a JFET. They are also introduced to vocabulary terms and formulas.

In this animated object, learners examine the operation of a summing operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

In this animated object, students examine the concept of wattage dissipation and the three Watt's Law formulas.

In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.

Learners examine three formulas than can be used to find dc power. Examples are given.
