Learners examine the changes in current and voltage values in a parallel circuit when open and short conditions develop. Ohm's Law calculations are shown, and a brief quiz completes the activity.
Learners identify five common types of open wounds: abrasions, avulsions, incisions, lacerations, and puncture wounds.
In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.
In this learning activity you'll review how an open in a series circuit affects current.
In this animated object, learners observe the changes inside the DC shunt motor that could cause the motor to break apart when its field coil opens. A short quiz completes the activity.
In this animated object, learners view the operation of an open-collector inverter with and without a pull-up resistor.
Students read an introduction to the electronic workbench and view a demonstration of how to open a file for circuit simulation.
In this animated activity, learners examine the difference between opens and shorts in an electrical circuit. A brief quiz completes the object.
Learners examine how air-to-open valves and air-to-close valves are used in different situations. A brief quiz completes the activity.
In this animated object, learners examine the PDF (portable document format), which has become the standard file format in the printing industry for the distribution of printable documents.
In this learning activity you'll identify TCP and UDP port states and how they behave during interaction.
In this animated object, learners examine the basic types of limit switches and how they are used.
Students read about the characteristics of the ideal operational amplifier and compare them with the industry standard LM741C.
In this animated lesson, students view the operation of an electromechanical relay. A brief quiz concludes the activity.
In this animated object, learners examine the signals produced at the N.O. (normally open) and N.C. (normally closed) outputs of sourcing and sinking four-wire sensors. A brief quiz completes the activity.
In this activity we will learn how vulnerable websites are open to cross site-scripting attacks (XSS).
Explore how to use an evidence bag including how to open it, place items inside, and seal it for the crime lab.
Learners study an animation of a spring-and diaphragm actuator controlling the opening of a flow valve.
