In this animated object, learners examine how a coil of wire provides more resistance to AC current flow than an uncoiled wire. This learning object contains audio.

Learners study the theory of operation for a ratio pyrometer that measures temperature. A short quiz completes the activity.

The learner studies how electrons travel from one atom to the next. Examples demonstrate how voltage is created by the use of a battery or through magnetism. A quiz completes the activity.

In this interactive object, learners analyze a series-parallel DC circuit problem in a series of steps. Immediate feedback is provided.

In this teaching and learning aid, the user can 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.
