In this screencast, learners examine the physical facets that determine the value of a capacitor.
Ohm's Law Practice Problems #3
By Patrick Hoppe
Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
Selector Switch Labeling
By Terry Bartelt
In this animated object, learners examine the method of interpreting the truth tables for two-position and three-position selector switches on ladder logic circuit diagrams.
Instantaneous Current Calculations of a De-Energizing RL Circuit (Using a TI-36X Calculator)
Students view a sample of the keystrokes used on a TI-36X calculator to solve for the instantaneous current of a de-energizing circuit.
Weight-Volume Relationships: Density
By Steve Whitmoyer
Students read an explanation of the use of weight-volume relationships and practice calculating density.
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.
