The use of the reciprocal key on the TI-86 scientific calculator is demonstrated in the solution of parallel resistors.

Learners examine a general approach to solving for the current through, the voltage across, and the power dissipated by each resistor in a series DC circuit. A three-resistor series circuit is used as an example.

Learners examine the concept of the RC time constant. The instantaneous voltage across the capacitor is calculated.

In this learning activity you'll follow the process of converting digital data into a series of analog signals.

Learners answer questions about internal combustion engines using a game board format. This learning object can be used individually, in small groups, or as a class activity to provide an alternative self-assessment tool.

In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.

In this interactive object, learners demonstrate the proper tightening sequence for mechanically joining two mating surfaces.

In this animated object, learners examine the operation of an optocoupler, specifically how it is connected to external components to provide interfacing and isolation and how it responds to excessive frequencies. A quiz completes the activity.

Learners read a description of the function of the coupling switch on an oscilloscope and how its setting affects measurements of DC, AC, and combined voltages. A brief quiz completes the activity.

You'll practice identifying the major components of an engine lathe.
