Learners read how nanotechnology is creating new jobs in emerging industries while making others obsolete. This colorful and animated activity also looks at the types of products being created through the use of technology and how educational institutions have responded.

Be the force to create a safer agricultural community by creating and presenting effective educational presentations. By informing others about biosecurity strategies, you’ll become a biosecurity advocate as you spread the word about its importance!

The learner views the operation of a transistor switching from saturation to cutoff. A brief quiz completes the activity.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.

Learners examine the operation of a DC Shunt motor and its characteristics. A quiz completes the activity.

In this interactive object, learners follow steps to find phase voltages in a partial three-phase power distribution circuit.

In this animated object, learners study how the internal parts of an AC synchronous motor interact with magnetic fields to cause rotation. A short quiz completes the activity.

In this animated activity, learners view the seven steps that are used to calculate voltage and current values throughout a common-emitter transistor amplifier.

In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.

In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.

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

In this drag-and-drop exercise, learners review the names of diagnostic tests and match them with their descriptions and the nursing actions that relate to them.

The superposition theorem is explained as it relates to dc circuit analysis. Examples are given.

Learners follow the steps for reducing all of the elements of a complex circuit to a single current source and a single source resistance to create a simple circuit. Several examples are given for dc circuits. The conversion between Thevenin and Norton is also presented.

In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.
