In this interactive object, learners view a practical application of a PLC Timer-On function.
Students read about the characteristics of the ideal operational amplifier and compare them with the industry standard LM741C.
Learners view the operation of a full-wave rectifier which has two diodes.
In this learning activity you'll build a resistor's color code based on the bands.
Learners examine the animated Timer-On Delay instruction and the Timer-Off Delay instruction of a PLC timer. A brief quiz completes the activity.
Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.
Learners read a description of torque and study the factors that cause its magnitude to change. A brief quiz completes the activity.
This learning activity uses a water pressure analogy to present the concept that voltage pressure is required to cause current flow.
Students work five practice problems to determine the Thevenin resistance of DC circuits.
In this learning activity you'll be introduced to the layout and operation of the solderless breadboard.
Learners view colorful animations showing the operation of a VR stepper motor.
In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.
In this interactive object, learners examine the operation of an inverting operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.
In this animated activity, learners see that changing the resistance value of the load in the secondary of a transformer causes current to vary in the primary.
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.
Learners read a description of inductors and view examples of inductors in series and in parallel.
Students view the parts and movements of a combustion engine in this animated activity. Each part is described.
In this animated object, students examine the concept of wattage dissipation and the three Watt's Law formulas.
