Learners study the factors that determine the frequency of an AC generator, such as the rotational speed of the armature or the number of stator poles.
The Frequency Generator: Miscellaneous Controls
By Terry Bartelt
Learners read a description of the DC offset function, the 50 ohm and 600 ohm output terminals, and the TTL/CMOS output terminal.
Op Amps 5: Non-Inverting Amplifier Circuit Resistance
By Todd Van De Hey
The learner will calculate basic circuit resistance.
Op Amps 3: The Inverting Amplifier
Describe the inverting op-amp configuration and calculate the circuit gain.
Direct-Operated, Pressure-Reducing Valves
By Terry Bartelt, Doyle Davis
In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.
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.
Series RL Circuit Vector and Circuit Analyzer
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
