In this screencast, learners examine the physical facets that determine the value of a capacitor.
The Open-Collector Logic Device
By Terry Bartelt
In this animated object, learners view the operation of an open-collector inverter with and without a pull-up resistor.
Methods of Producing Electricity
In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
Current in a Series Circuit
In this learning activity you'll determine what happens to current flow in a series circuit when the resistance is changed.
Parallel Circuit Analysis Practice Problems: Circuit #7
By Patrick Hoppe
In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.
Adding and Subtracting Signed Numbers
By Mona Wenrich
Learners follow the steps for adding and subtracting signed numbers and complete practice exercises.
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.
