Unformatted text preview: Caleb Simms Lab 3: Transistors Introduction: In this lab, some uses of transistors are examined. In Part A we want to find the value of our transistor. To do this we wire up the circuit shown below. We then use 7 different values of R ranging from 10k to 10M and measure the current on the collector ( c i ). We set the voltage drop from the base to the emitter ) ( BE V as .6V. Therefore, the current voltage drop across the two resistors must be 4.4V. So the current along the base k R i b 5 4 . 4 + = . This allows us to find because we know = b c i i . After using the circuit in part A to outline the basic properties of the transistor, it is put to use in the Emitter-Follower circuit as shown. This circuit outlines basic properties of the transistor, showing how it can be saturated and used to load a circuit. Part C is a wiring of a common-emitter amplifier, set up as shown. The purpose of the lab is to explore the basic functions of transistors....
