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.

Learners view a sample of the keystrokes from a TI-35X or 36X calculator that are required to solve for the instantaneous voltage of a charging RC circuit.

In this learning activity you'll read the procedures for using the vertical function of an oscilloscope and view illustrations of waveforms.

Learners examine the changes in current and voltage values in a parallel circuit when open and short conditions develop. Ohm's Law calculations are shown, and a brief quiz completes the activity.

This learning object shows the symbols used to represent the type of pulse required at the clock input to activate flip-flops.

In this animated object, learners examine three different types of multivibrators: astable, monostable, and bistable. A brief quiz completes the activity.

Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.

Learners read how to set up a TI-86 calculator. The process is demonstrated and examples are given.

The learner examines the setup process of a TI-83 Plus calculator. The process is demonstrated and examples are given.
