In this animated object, learners examine the two types of optical encoders used in automation applications: incremental and absolute. A brief quiz completes the activity.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.

Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.

In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.

Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.

You'll learn to identify antenna terms and concepts.

You'll learn some concepts related to radio frequency modulation.

You'll learn to identify frequency bands of the electromagnetic spectrum licensed by the FCC.
