In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied. A brief quiz completes the activity.

In this learning activity you'll review how a short affects current flow and voltage in a series circuit.

The student takes a quiz on lathe operations between centers.

Students read a description of the function generator and view a graphic that labels its parts.

Learners view a vector diagram for a series RC circuit and read information concerning the voltage across each component, the total voltage, and the phase angle.

Learners read about the vector diagram for a parallel RL circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.

Learners view a vector diagram for a series RL circuit. Information on the voltage across each component, the total voltage, and the phase angle is included.

In this learning activity you'll review various types of common components used in electronics and view their schematic diagram symbols.

In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.
