Lab 4: Transistors

Intro:

The purpose of this lab is to get acquainted with transistors by finding gain and saturation point.

Experiment:

Finger switch

Data:

Milliamps through A1 Milliamps through A2

0                                  0

.28                               53.3

.3                                 53.9

.45                               61.1

.6                                 65.8

.75                               69.0

Analysis:

Graph

The gain of the transistor is the slope in the beginning which has a slope of 190.  The saturation is the flat line about 70 milliamps.
