BJTAppls

This App is meant to show the inner workings of a bipolar junction transistor operating as both an amplifier and as a binary switch.

It helps to show some concepts that maybe difficult to comprehend from a static picture in a textbook.

The first sequence of images "Struct" shows the steps necessary to create the structure of a common-emitter transistor configured to operate as an amplifier and then as a binary switch.

The second sequence of images "Amp" simply shows the transistor operating as an amplifier.
Hit the "PlayAll" button and just watch the operation.

The third sequence of images "Switch" simply shows the transistor operating as a binary switch.
Hit the "PlayAll" button and just watch the operation.

Note:
This is a now a free App but uses interstitial ads that will display, if available, after the segmentation control is selected. There are no banner ads and no in-app purchases.
