Learners examine the operation of a DC Shunt motor and its characteristics. A 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.
Brain Exercise: Visualization #1
By Glenn Sokolowski
In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object. Front, side, and top orthographic views are shown.
Three Phase Wye Transformer Calculations
By James Bourassa
In this interactive object, learners follow steps to find phase voltages in a partial three-phase power distribution circuit.
Continuous-Cycle Reciprocation Circuit
By Terry Bartelt
This animated lesson shows how a ladder circuit causes the cylinder of a hydraulic circuit to continuously extend and retract after a Start button has been pressed.
AC Voltage Conversion Problems
By John Rosz, Terry Bartelt
Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
AC Current Flow
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
Oscilloscope: DC Voltage Measurements
Learners follow step-by-step instructions for using an oscilloscope to measure DC voltages.
Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.
Series RC Circuit Practice Problems
In this interactive object, students calculate capacitive reactance, phase angle, impedance, and power in series RC circuits.
