In this interactive object, learners answer nine questions about series and parallel circuits. Immediate feedback is provided.

Learners study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.

Learners examine the different types of lines used on a P&ID diagram and the types of connections they represent. They test their knowledge in a matching exercise.

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

In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.

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

Learners observe animations showing how data is converted between serial and parallel flow.

Learners follow a methodical approach for the dc analysis of series-parallel circuits.

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

You'll practice calculating circuit gain and output voltage for the non-inverting amplifier.
