Students read the terms associated with the Bipolar Junction Transistor (BJT) . They also view formulas for dc current and voltage.

In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.

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.
