Learners apply the principles associated with Boyle’s Law.

Learners read a step-by-step approach on how to connect an ohmmeter when making measurements in this interactive lesson.

Learners observe the waveforms in a circuit in which a triac controls the brightness of a lamp’s light. A brief quiz completes the activity.

In this animated object, learners examine the causes of air leaks and read how to repair them. The object includes audio.

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.

Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.

In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.

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

You'll practice solving problems using the rule for multiplying powers with the same base.
