Learners examine the properties that determine capacitance.
Series Circuit Analysis Practice Problems: Circuit #5
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.
Weight-Volume Relationships: Saturated Unit Weight
By Steve Whitmoyer
Students read how to determine and calculate the saturated unit weight for a given sample of soil or aggregate, based on the weight-volume relationship. Practice problems complete the activity.
The Transistor Symbol
By Terry Bartelt
In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.
Troubleshooting a Faulty JK Flip-Flop
In this animated object, learners examine the recommended procedure for troubleshooting a defective JK flip-flop using a logic pulser and probe.
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.
