Students read about the concept of true power and view examples of how it is dissipated as heat is provided.
Assembling a Circuit from a Schematic Diagram
By Terry Bartelt
In this animated object, students examine the steps for wiring an electrical circuit from reading a schematic diagram.
Effects of a Rheostat in a Series-Parallel Circuit
Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.
In this animated object, learners examine different types of pneumatic actuators, cylinders, and motors.
Hydrocarbon Gas Sensor
Learners study how a hydrocarbon gas sensor operates and why it is used. A short quiz completes the activity.
Series RC Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Parallel RC Circuit Vector and Circuit Analyzer
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Capacitive Reactance Practice Problems
By Patrick Hoppe
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
Vector Diagram for a Series RC Circuit
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.
Transformer Practice Problems
Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.
