➄ The “a2” coefficient of the Linear Fit line is the slope of the linear region. Record the value of
the slope.
• The slope can be interpreted as follows:
slope
= ∆
I
c
∆
I
b
= β
where
β
is called current gain of the transistor.
➅
Record the current gain of the 2N3904 transistor.
current gain = __________
Questions
➀
How does the general shape of the plot for the transistor compare to the plot of current versus
voltage for a diode?
➁
What is the current gain of the 2N3904 transistor?
