Transistor Switching

Introduction: The purpose of this lab is to learn about transistors and how to use them.

Procedure: 
Step 1: First we model the following circuit with the proper resistors, led and etc.

Step 2: Assemble the breadboard. 

 

Step 3: Here we are turning on the switch from on to off by connecting them with our fingers. 

 

 Step 4:  The last circuit below was tested using a potentiometer to change the current entering the base while data was connected using two ammeters.

 

Step 5: Record the data.
