In this animated lesson, students view the operation of an electromechanical relay. A brief quiz concludes the activity.
In this screencast, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts.
In this animated activity, learners view the flip-flop and read about its outputs, the information it stores, and its storage conditions. A quiz completes the lesson.
Students view the layout and operation of a digital logic probe.
Learners view the scene of a suspicious death and select the evidence that needs to be collected.
Learners view maps of Australia and New Zealand and locate the territories and states of these countries in an interactive exercise.
Learners view an animation showing how the volume of a given quantity of gas varies directly with its temperature.
Learners view animations showing methods of measuring the pH level of a solution using litmus paper and electronic instruments.
Students read an introduction to the electronic workbench and view a demonstration of how to open a file for circuit simulation.
Students view the equations used to determine the ac parameters of the transistor circuit.
Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.
In this interactive object, learners view a practical application of a PLC Timer-On function.
Students read the terms associated with the Bipolar Junction Transistor (BJT) . They also view formulas for dc current and voltage.
This animated object illustrates the events leading to the migration of phagocytes into areas of tissue damage and/or bacterial presence. Learners view bacterial cell phagocytosis, its subsequent enzymatic digestion, and exocytosis.
Students read about the concept of true power and view examples of how it is dissipated as heat is provided.
Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.
In this animated activity, students view how the Wheatstone bridge is used to activate a temperature alarm. A short quiz completes the lesson.
Students view the steps for dividing complex numbers in Excel.
Students view the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous voltage of a charging RC circuit.
Students view the parts and movements of a combustion engine in this animated activity. Each part is described.
