In this interactive object, students calculate capacitive reactance, phase angle, impedance, and power in series RC circuits.
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.
Single-Phase Motors: Introduction to Phase-Splitting
By Terry Bartelt, Terry Fleischman
Learners will understand how the interaction of the armature magnetic field and the rotating stator field cause the rotor of a single-phase AC motor to turn.
Capacitive Probe Sensors
Learners study the operation of capacitive probe sensors used to measure levels in a tank.
The Transfer Functions: RC Low-Pass Filter with a Bode Plot
By Patrick Hoppe
Students read how the transfer function is developed for an RC low-pass filter. A straight line Bode plot is drawn through close approximations.
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.
Parallel RC Circuit Vector and Circuit Analyzer
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
