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.

In this interactive object, learners work 12 problems dealing with dc circuit analysis.

Learners observe the four functions of oil in a hydraulic system.

Learners will identify the number of significant digits in practice problems.

In this animated object, learners examine processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.

In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.

In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.

Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

Learners read how inches of water column is used as a unit of pressure measurement. Practical applications and a conversion formula to psi are included.
