In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.
In this animated activity, learners view the seven steps that are used to calculate voltage and current values throughout a common-emitter transistor amplifier.
Learners view the operation of an NPN transistor in the active region.
Students view the design and function of an ac model for a transistor circuit.
Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.
The learner views the operation of a transistor switching from saturation to cutoff. A brief quiz completes the activity.
Students read about the concepts of saturation and cutoff. They view diagrams that illustrate the interaction of the load line and the family of curves.
Students view drawings of the emitter resistor bypass capacitor.
