In this animated activity, learners view the following physics concepts in action: force, friction, horsepower, work, power, inefficiency, resistance, inertia, and energy.

Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.

Students read how to use the DEGREES() function to convert radians to degrees.

In this interactive object, students calculate capacitive reactance, impedance, current, and power in parallel RC circuits.

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.

A sample exam for DC/AC I, unit # 12 is presented to the students. This unit covers transformers.

Learners study the effect of reflected and transmitted energy on the measurement of emitted energy by a non-blackbody. A short quiz completes the activity.
