Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.

In this colorful and animated activity, learners study the operation of a needle valve and the operation of the needle valve with a check valve. A brief quiz completes the activity.

Learners read about the vector diagram for a parallel RC circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.

Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.

Learners read an explanation of variation and how it can make a process unpredictable. They distinguish between common and special causes of variation in a brief exercise at the end of the lesson.

Learners read the definitions of various water forms and locate the bodies of water on a map.

Students read about the three main classes of amplifiers and view graphical representations of the collector current and circuit.

In this animated object, learners see how a time proportioning operational amplifier varies an average DC voltage. A brief quiz completes the activity.
