Students view the mathematical expression of a sinusoidal waveform with respect to time (t) and solve five problems. The answers are provided so students may check their work.

Learners observe how an optical pyrometer is used to take temperature measurements without making physical contact with the object being measured.

Learners study the factors that determine the frequency of an AC generator, such as the rotational speed of the armature or the number of stator poles.

Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.

Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.

Learners view animations and video clips showing how power is transmitted from one energized coil to another.

Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.

Learners study how a circuit converts the AC output of a linear voltage differential transformer (LVDT) into variable DC voltage. It is recommended that learners view the learning object IAU7807, “The LVDT: A Linear Voltage Differential Transformer in Action” before going through this object.

Learners follow a step-by-step explanation of how to test fuses and circuit interrupting devices.

This game is designed to prepare you for your magnetism quiz.
