Ohm's Law: Power
By Tim Tewalt, Patrick Hoppe
Learners study animated rheostat settings that show how varying the current flow affects the amount of power that is dissipated in a series circuit. Nine review questions complete the activity.
The Closed-Loop Velocity Servo System
By Terry Bartelt
In this animated object, learners examine the operation of a closed-loop system that maintains the speed of a conveyer belt as heavy boxes are placed or removed.
In this animated object, learners examine how various types of positive and non-positive displacement hydraulic pumps work.
Voltage Sources in Parallel
The effect of connecting voltage sources in parallel to increase amperage to a load is presented.

By Patrick Hoppe
Students view a demonstration of the Current Divider Rule with the use of complex numbers. Examples are given.
The Voltage Divider Rule with Complex Numbers
Students read an explanation of the Voltage Divider Rule with complex numbers. Examples are given.
Superposition Theorem with Complex Numbers
Students read an explanation of "superposition" as a technique for ac circuit analysis. Complex numbers are used.
Total Impedance of a Series Circuit Using Complex Numbers
Students view several examples of how to determine the total impedance of a series circuit. The "j" term is used in all of the calculations.
Total Impedance of a Parallel Circuit Using Complex Numbers
