Learners examine the properties that determine capacitance.
How Current Requires Voltage
By Terry Bartelt
This learning activity uses a water pressure analogy to present the concept that voltage pressure is required to cause current flow.
In this animated object, students examine the concept of wattage dissipation and the three Watt's Law formulas.
Transistor Fundamentals: Emitter-Biased NPN Transistor
By Patrick Hoppe
Students view a dc analysis of an emitter-biased NPN transistor.
Electrical Units, Abbreviations, and Symbols
In this learning activity you'll read introduction to electrical quantities, units, and symbols and test their knowledge in a matching exercise.
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.
