Students solve problems on the determination of total inductive reactance of series-parallel inductors.
Ohm's Law: Current
By Tim Tewalt, Patrick Hoppe
Learners study animated rheostat settings that show how current flow is inversely proportional to resistance. Ten review questions complete the learning object.
By Terry Bartelt
In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. They then answer six multiple-choice questions.
Students examine the four factors that affect resistance of a wire: temperature, length, diameter, and the type of material from which it is made. A short quiz completes the activity.
Operation of Full-Wave Bridge Rectifier
By Matthew Treu
In this learning activity you'll explore the operation of a full-wave bridge rectifier circuit.
Series RL Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Parallel RL Circuit Vector and Circuit Analyzer
This learning activity presents information on how the type of material used for the core material of an inductor affects the inductors value in henries.
Capacitive Reactance Practice Problems
By Patrick Hoppe
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
This learning activity describes the physical properties that affect the inductance, in henries, of an inductor.
Cylinders: Basic Terminology
You'll practice defining terms relating to cylinders and identifying parts of cylinders.
