In this animated object, learners examine the basics of capacitance and capacitors.
Incremental Optical Encoders
By Terry Bartelt
Learners study the operation and characteristics of an incremental optical encoder used in automated manufacturing applications. A brief quiz completes the activity.
Three-Phase Delta Transformer Calculations
By James Bourassa
Using a memory shortcut for calculations, the learner determines line and phase values of current in a three-phase AC configuration. Practice problems complete the activity.
Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity.
Total Impedance of a Series Circuit Using Complex Numbers
By Patrick Hoppe
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.
Parallel RC 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.
In this interactive object, learners examine the physical facets that determine the value of a capacitor. A brief quiz completes the activity.
This learning activity presents information on how the type of material used for the dielectric of a capacitor affects the capacitor's value in farads.
Capacitive Reactance Practice Problems
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
The Electrostatic Charge of a Capacitor
In this animated activity, learners examine the conversion of electrical energy into an electrostatic charge within the dielectric material of a capacitor.
