In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

Using the principle of Pascal's Law, the learner will interpret the gauge readings in a hydraulic system to determine when the system is operating properly under various load conditions and when there is a defect.

Students work six practice problems to determine the total capacitance of a series circuit. Immediate feedback is given.

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.

Learners read how to use a lumber rule to quickly and accurately estimate board feet. They then use virtual samples to practice the process.

Learners view videos of law enforcement and corrections officers describing their jobs and the opportunities in their fields. Because this object contains large video files, it is best viewed using a high band width connection. Low band widths will result in longer download time and video delays.

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.
