In this animated object, learners study how displacement level sensors are used to measure the level of liquid in a tank.

Learners observe the animated operation of an astable mulivibrator using a 555 IC (integrated circuit) chip and external components.

The learner will apply the three formulas used to find the total resistance of three types of parallel resistor circuit configurations.

In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.

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

In this interactive object, learners examine the physical facets that determine the value of a capacitor. A brief quiz completes the activity.

This learning activity presents information on how the type of material used for the dielectric of a capacitor affects the capacitor's value in farads.

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

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.
