Learners examine an animation that shows how an AC voltage is produced as an armature rotates within a magnetic field. Ten review questions complete the learning object.
Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.
In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
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.
Learners read an explanation of how the Magnetron Ignition System uses a solid state switching component, a step-up transformer, and magnetism to provide a high voltage spark in a one-cylinder combustion engine.
