Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.

Students view a dc analysis of a base-biased NPN transistor.

Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.

Students view a dc analysis of an emitter-biased NPN transistor.

In this animated object, learners examine the operation of a zener diode in the forward and reverse bias conditions. A quiz completes the activity.

In this animated activity, learners examine the operation of the SCR, including how it is biased and how it is turned off. A brief quiz completes the object.

In this interactive and animated object, learners examine the operation of a semiconductor diode when it is forward and reverse biased. A brief quiz completes the activity.

The learner will identify ways to overcome barriers to critical thinking and problem-solving including false memories, personal biases and prejudices, and physical and emotional hindrances.
