Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Ohm's Law Practice Problems #4
By Patrick Hoppe
Learners review Ohm's Law and 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.
Charging Time Constants of an RC Circuit
By Terry Bartelt
In this animated object, students view an explanation of how current, voltage, and the charge on a capacitor of a series RC circuit change during five time constants. A short quiz completes the activity.
Total Impedance of a Parallel Circuit Using Complex Numbers
Students read how to determine the total impedance of a parallel circuit using complex numbers. The "J" term is used in the calculations.
Capacitive Proximity Sensor Target Considerations
In this animated object, learners examine the factors that determine how well a capacitive proximity sensor can detect an object. Those factors include size, position, and the materials from which the target is made. A brief quiz completes the activity.
Series RC Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Inductive Reactance Practice Problems
Students solve problems on the determination of total inductive reactance of series-parallel inductors.
Series RL Circuit Vector and Circuit Analyzer
Parallel RC Circuit Vector and Circuit Analyzer
This learning activity presents information on how the type of material used for the core material of an inductor affects the inductors value in henries.
