The learner will...review the process for successfully completing a weld procedure specification for weld testing in the educational setting.

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

Learners view the operation of an NPN transistor in the active region.

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

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 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.

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.

In this learning activity you'll identify abbreviations that represent quantities associated with electrical circuits.

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

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

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.

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

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!

Students follow the steps that are required to select a transformer with the proper ratings. Voltage, frequency, current, and KVA are considered.

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

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!
