In this interactive object, learners solve for the current through each resistor, the voltage across each resistor, and the power dissipated.

In this animated object, learners examine the mechanical configuration of a three-way switch and how it operates in a circuit. They also view diagrams showing the use of an ohmmeter to determine the electrical connections.

Learners view the operation of a full-wave rectifier which has two diodes.

Learners examine the fundamental operation of a difference operational amplifier. A brief quiz completes the activity.

Students read the rules used in multiplying and dividing signed numbers. They view examples and work practice problems.

Students read how to organize their work when multiplying more than two signed numbers. A review and practice problems complete the activity.

Learners follow the steps for adding and subtracting signed numbers and complete practice exercises.
