Learners examine the theory of operation for a combustible gas detector. A brief quiz completes the activity.

In this learning activity, learners will learn to calculate the average voltage produced by half-wave and full-wave rectifiers.

In this interactive object, learners work 11 problems covering atomic structure, conductors, and insulators.

In this interactive and animated object, learners examine how dc voltages develop across capacitors that are connected in series and in parallel.

Students solve problems on the determination of total inductive reactance of series-parallel inductors.

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

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased from 0 Hz towards resonance.
