Learners examine the operation of a DC Shunt motor and its characteristics. A quiz completes the activity.
Pulse Train Fundamentals
By Patrick Hoppe
Learners examine the fundamentals of a pulse train. Concepts such as time on, time off, duty cycle, period, and frequency are covered.
Feedback System Application
By Terry Bartelt
In this animated and interactive object, learners examine a heat exchanger as an example of an automated closed-loop system.
In this learning activity you'll explore how a fuse de-energizes a parallel circuit when too many lamps are connected to a power outlet.
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-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.
Voltage Divider Rule (VDR)
By Terry Fleischman, Patrick Hoppe
Students review the Voltage Divider Rule and work practice problems.
Calculating Horsepower, RPM, and Torque
By James Bourassa, John Rosz
In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
