In this animated activity, learners examine why various materials are conductors, insulators, or resistors of current. A short quiz completes the learning object.

Learners study the interaction between the conductors of the stator and the armature inside a DC motor, which causes the shaft to rotate. 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 work 11 problems covering atomic structure, conductors, and insulators.
