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

Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.

In this interactive object, learners calculate a centroid of a composite area by first creating a chart. A short quiz completes the activity.

In this interactive object, students work parallel circuit analysis problems. They solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

Students answer five questions concerning magnetism.

Learners solve for voltage, current, and power in a single source, six-resistor circuit. A help screen is provided.

Learners solve 14 problems related to voltage, current and power in a single source, six-resistor circuit. A help screen is provided.

Learners examine a series-parallel circuit and solve 14 problems related to voltage, current and power. A help screen is provided.
