Learners examine the operation of a DC Shunt motor and its characteristics. A quiz completes the activity.
Impedance: Series to Parallel Conversion
By Patrick Hoppe
Students view the formulas to be used to convert a series impedance to a parallel impedance.
By Terry Bartelt
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.
DC Circuit Analysis: The Series Circuit
Learners examine a general approach to solving for the current through, the voltage across, and the power dissipated by each resistor in a series DC circuit. A three-resistor series circuit is used as an example.
Series-Parallel Circuit Analysis Practice Problems: Circuit 2
In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.
Series-Parallel DC Circuits Analysis
Learners follow a methodical approach for the dc analysis of series-parallel circuits.
Series-Parallel Practice Problems Circuit 4
In this interactive object, learners work 12 problems dealing with dc circuit analysis.
Ohm's Law Practice Problems #1
Learners review Ohm's Law and then 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.
Abbreviations Representing Electrical Quantities
In this learning activity you'll identify abbreviations that represent quantities associated with electrical circuits.
Voltage Divider Rule (VDR)
By Terry Fleischman, Patrick Hoppe
Students review the Voltage Divider Rule and work practice problems.
