The learner will understand the design of a planetary gear drive and its advantages and disadvantages.

In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.

The learner will be able to represent steady-state AC sinusoidal signals using phasors, which will lead to a simplified technique of analyzing AC circuits in a very similar way that we analyze DC circuits.

Learners examine how voltages and currents vary in a series RLC circuit as the applied frequency changes.

In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.

In this animated activity, learners study how a PLC performs a shift operation. The learning object covers data movement, data entry, PLC wiring, PLC shift register introductions, and programming for a paint can operation.

Users read work instructions and view a drawing and calculations for turning on a lathe using a digital readout.

Students follow steps to determine the number of inputs that can be driven by a specific IC. A sample problem is given.

Learners read how to create a spreadsheet to determine the voltage drop across a resistor in an AC circuit. The complex functions explained in other learning objects are used in this example.
