Students read about the concept of true power and view examples of how it is dissipated as heat is provided.
Transistor DC Analysis Practice Problems: Circuit #4
By Patrick Hoppe
Learners analyze an emitter-biased npn transistor circuit. A "help" screen is available.
Analog Position Control
By Terry Bartelt
In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.
Series-Parallel Circuit Analysis Practice Problems: Circuit 3
In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.
Instantaneous Voltage Calculations of a Charging RC Circuit (Calculator TI-35X orTI-36X)
Learners view a sample of the keystrokes from a TI-35X or 36X calculator that are required to solve for the instantaneous voltage of a charging RC circuit.
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.
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.
Capacitive Reactance Practice Problems
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
Vector Diagram for a Series RC Circuit
Learners view a vector diagram for a series RC circuit and read information concerning the voltage across each component, the total voltage, and the phase angle.
Transformer Practice Problems
Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.
